Dates reviewed: 4 October 2026. Fixed annual observances are carried into 2027 from primary sources. Movable events use published 2027 calendars or clearly stated recurrence rules. Local festival observance, moon-sighting dates and office closures can differ. Recheck the linked source before a time-sensitive campaign.
How to read the calendar
Official observance means a recognised awareness or commemorative date; it does not automatically mean a public holiday. Religious and regional festivals are labelled by the community or calendar used. Organiser campaigns include dates such as Earth Hour. Cultural and commercial occasions include Valentine's Day, Halloween and Black Friday.
The date badge explains the evidence: a published 2027 primary source, a fixed annual date, a date calculated from the organiser's recurrence rule, or a provisional date needing local confirmation. A source may publish its annual campaign theme later than its date. No unannounced 2027 theme is assumed here.
2027 calendar by month
January · February · March · April · May · June · July · August · September · October · November · December
January 2027
Choose the buyer questions you want to answer this year before filling the calendar. January works well for explainers, planning checklists and practical product comparisons. Regional harvest festivals need local language and cultural review.

Help customers finish the year well
Service business: publish confirmed holiday hours and the support route for existing customers.
Product business: show setup and care instructions that reduce avoidable support questions.
B2B: explain one lesson learned from a project without exposing confidential client information.
Turn a date into a useful post
Start with the audience's question. Then choose the occasion, if one helps. An engineering company can use Engineers' Day to explain a specification buyers misunderstand. A textile business can use National Handloom Day to show a real process and credit the maker. A software company can use Global Accessibility Awareness Day to demonstrate an improvement people can test.
For each post, write down five things: who it helps, what question it answers, what evidence you can show, what the reader can do next and how you will judge the response. A date gives you timing. Your expertise gives the post its value.
A simple monthly planning routine
Pick one business goal and a specific audience need
Review sales enquiries, customer-support questions and existing content for useful topics
Choose a few relevant dates and plan around real lead times
Assign a format, owner, reviewer and publishing time zone to each post
Review facts, cultural context, accessibility, permissions and offer terms before approval
After publishing, record the meaningful result and what to change next month
Keep evergreen help in the plan: comparisons, demonstrations, FAQs, customer stories and product guidance. Leave room for timely updates. Set a publishing pace your team can sustain; a filled spreadsheet is not a reason to publish a weak post.
Use the editable 2027 templates
Get the editable 2027 planning kit
The download includes an Excel workbook with a content plan, a monthly campaign plan, twelve worked examples, a sourced date library and instructions. The CSV files let you import the date library or start a simple post plan in another spreadsheet tool.
Open the XLSX in Excel, or upload it through Google Sheets' import flow. Check the dropdowns and date formatting after import. Use one row per post and duplicate rows as needed. The planner does not publish or schedule posts, and CSV files do not preserve formatting, filters or dropdowns.
The examples are original planning demonstrations. Replace their draft wording and placeholders with your own approved facts, links and offers. They are not client results or ready-approved advertising claims.
Build trust before asking for the enquiry
HubSpot's inbound approach centres on useful content and long-term customer relationships. Its calendar guidance also separates campaign planning, individual posts and reusable content. We use those ideas here to connect dates with a buyer need, a useful next action and a reviewable result. This is an independently created Debate Marketers resource, not a HubSpot template or endorsement. HubSpot's inbound methodology · HubSpot's social content calendar guidance
For a business, that can be straightforward: answer a real question in the post, give people a useful worksheet or guide, then make a relevant conversation easy to start. Keep the resource request separate from any future marketing signup.
Frequently asked questions
Are these all official holidays?
No. The calendar separates public holidays, official observances, religious festivals, organiser campaigns and cultural or commercial occasions. For office closures, use the relevant employer, government and regional holiday notification.
Why do some 2027 festival dates differ across calendars?
Location, religious tradition, lunar timing and the purpose of a calendar can change the date shown. A central-government holiday date can differ from a local celebration or ritual calendar. Keep the source and region attached to the date rather than treating one date as universal.
Is Mother's Day the same worldwide?
No. The May date here uses the US second-Sunday rule. Other countries observe Mother's Day on different dates. Check your audience before reusing a campaign across markets.
Can I use this as a Google Sheets social media calendar?
Yes. Import the Excel or CSV file into Google Sheets and check the imported dates and controls. The downloadable workbook is editable; no Google account access or scheduling integration is included.
Do I need to subscribe to get the templates?
Use your email to request the download. This request is for one-time resource access. It does not sign you up for marketing emails.
How often should I update the plan?
Review the next month before it starts and check the coming week for changed offers, availability, events or sensitive news. Recheck provisional dates closer to publication. Keep the source links with the plan so a correction is easy to trace.

Dates reviewed: 4 October 2026. Fixed annual observances are carried into 2027 from primary sources. Movable events use published 2027 calendars or clearly stated recurrence rules. Local festival observance, moon-sighting dates and office closures can differ. Recheck the linked source before a time-sensitive campaign.
How to read the calendar
Official observance means a recognised awareness or commemorative date; it does not automatically mean a public holiday. Religious and regional festivals are labelled by the community or calendar used. Organiser campaigns include dates such as Earth Hour. Cultural and commercial occasions include Valentine's Day, Halloween and Black Friday.
The date badge explains the evidence: a published 2027 primary source, a fixed annual date, a date calculated from the organiser's recurrence rule, or a provisional date needing local confirmation. A source may publish its annual campaign theme later than its date. No unannounced 2027 theme is assumed here.

Choose the buyer questions you want to answer this year before filling the calendar. January works well for explainers, planning checklists and practical product comparisons. Regional harvest festivals need local language and cultural review.

Help customers finish the year well
Service business: publish confirmed holiday hours and the support route for existing customers.
Product business: show setup and care instructions that reduce avoidable support questions.
B2B: explain one lesson learned from a project without exposing confidential client information.
Turn a date into a useful post
Start with the audience's question. Then choose the occasion, if one helps. An engineering company can use Engineers' Day to explain a specification buyers misunderstand. A textile business can use National Handloom Day to show a real process and credit the maker. A software company can use Global Accessibility Awareness Day to demonstrate an improvement people can test.
For each post, write down five things: who it helps, what question it answers, what evidence you can show, what the reader can do next and how you will judge the response. A date gives you timing. Your expertise gives the post its value.
A simple monthly planning routine
Pick one business goal and a specific audience need
Review sales enquiries, customer-support questions and existing content for useful topics
Choose a few relevant dates and plan around real lead times
Assign a format, owner, reviewer and publishing time zone to each post
Review facts, cultural context, accessibility, permissions and offer terms before approval
After publishing, record the meaningful result and what to change next month
Keep evergreen help in the plan: comparisons, demonstrations, FAQs, customer stories and product guidance. Leave room for timely updates. Set a publishing pace your team can sustain; a filled spreadsheet is not a reason to publish a weak post.
Use the editable 2027 templates
Get the editable 2027 planning kit
The download includes an Excel workbook with a content plan, a monthly campaign plan, twelve worked examples, a sourced date library and instructions. The CSV files let you import the date library or start a simple post plan in another spreadsheet tool.
Open the XLSX in Excel, or upload it through Google Sheets' import flow. Check the dropdowns and date formatting after import. Use one row per post and duplicate rows as needed. The planner does not publish or schedule posts, and CSV files do not preserve formatting, filters or dropdowns.
The examples are original planning demonstrations. Replace their draft wording and placeholders with your own approved facts, links and offers. They are not client results or ready-approved advertising claims.
Build trust before asking for the enquiry
HubSpot's inbound approach centres on useful content and long-term customer relationships. Its calendar guidance also separates campaign planning, individual posts and reusable content. We use those ideas here to connect dates with a buyer need, a useful next action and a reviewable result. This is an independently created Debate Marketers resource, not a HubSpot template or endorsement. HubSpot's inbound methodology · HubSpot's social content calendar guidance
For a business, that can be straightforward: answer a real question in the post, give people a useful worksheet or guide, then make a relevant conversation easy to start. Keep the resource request separate from any future marketing signup.
Frequently asked questions
Are these all official holidays?
No. The calendar separates public holidays, official observances, religious festivals, organiser campaigns and cultural or commercial occasions. For office closures, use the relevant employer, government and regional holiday notification.
Why do some 2027 festival dates differ across calendars?
Location, religious tradition, lunar timing and the purpose of a calendar can change the date shown. A central-government holiday date can differ from a local celebration or ritual calendar. Keep the source and region attached to the date rather than treating one date as universal.
Is Mother's Day the same worldwide?
No. The May date here uses the US second-Sunday rule. Other countries observe Mother's Day on different dates. Check your audience before reusing a campaign across markets.
Can I use this as a Google Sheets social media calendar?
Yes. Import the Excel or CSV file into Google Sheets and check the imported dates and controls. The downloadable workbook is editable; no Google account access or scheduling integration is included.
Do I need to subscribe to get the templates?
Use your email to request the download. This request is for one-time resource access. It does not sign you up for marketing emails.
How often should I update the plan?
Review the next month before it starts and check the coming week for changed offers, availability, events or sensitive news. Recheck provisional dates closer to publication. Keep the source links with the plan so a correction is easy to trace.

Dates reviewed: 4 October 2026. Fixed annual observances are carried into 2027 from primary sources. Movable events use published 2027 calendars or clearly stated recurrence rules. Local festival observance, moon-sighting dates and office closures can differ. Recheck the linked source before a time-sensitive campaign.
How to read the calendar
Official observance means a recognised awareness or commemorative date; it does not automatically mean a public holiday. Religious and regional festivals are labelled by the community or calendar used. Organiser campaigns include dates such as Earth Hour. Cultural and commercial occasions include Valentine's Day, Halloween and Black Friday.
The date badge explains the evidence: a published 2027 primary source, a fixed annual date, a date calculated from the organiser's recurrence rule, or a provisional date needing local confirmation. A source may publish its annual campaign theme later than its date. No unannounced 2027 theme is assumed here.

January 2027
Choose the buyer questions you want to answer this year before filling the calendar. January works well for explainers, planning checklists and practical product comparisons. Regional harvest festivals need local language and cultural review.

Help customers finish the year well
Service business: publish confirmed holiday hours and the support route for existing customers.
Product business: show setup and care instructions that reduce avoidable support questions.
B2B: explain one lesson learned from a project without exposing confidential client information.
Turn a date into a useful post
Start with the audience's question. Then choose the occasion, if one helps. An engineering company can use Engineers' Day to explain a specification buyers misunderstand. A textile business can use National Handloom Day to show a real process and credit the maker. A software company can use Global Accessibility Awareness Day to demonstrate an improvement people can test.
For each post, write down five things: who it helps, what question it answers, what evidence you can show, what the reader can do next and how you will judge the response. A date gives you timing. Your expertise gives the post its value.
A simple monthly planning routine
Pick one business goal and a specific audience need
Review sales enquiries, customer-support questions and existing content for useful topics
Choose a few relevant dates and plan around real lead times
Assign a format, owner, reviewer and publishing time zone to each post
Review facts, cultural context, accessibility, permissions and offer terms before approval
After publishing, record the meaningful result and what to change next month
Keep evergreen help in the plan: comparisons, demonstrations, FAQs, customer stories and product guidance. Leave room for timely updates. Set a publishing pace your team can sustain; a filled spreadsheet is not a reason to publish a weak post.

The download includes an Excel workbook with a content plan, a monthly campaign plan, twelve worked examples, a sourced date library and instructions. The CSV files let you import the date library or start a simple post plan in another spreadsheet tool.
Open the XLSX in Excel, or upload it through Google Sheets' import flow. Check the dropdowns and date formatting after import. Use one row per post and duplicate rows as needed. The planner does not publish or schedule posts, and CSV files do not preserve formatting, filters or dropdowns.
The examples are original planning demonstrations. Replace their draft wording and placeholders with your own approved facts, links and offers. They are not client results or ready-approved advertising claims.

HubSpot's inbound approach centres on useful content and long-term customer relationships. Its calendar guidance also separates campaign planning, individual posts and reusable content. We use those ideas here to connect dates with a buyer need, a useful next action and a reviewable result. This is an independently created Debate Marketers resource, not a HubSpot template or endorsement. HubSpot's inbound methodology · HubSpot's social content calendar guidance
For a business, that can be straightforward: answer a real question in the post, give people a useful worksheet or guide, then make a relevant conversation easy to start. Keep the resource request separate from any future marketing signup.
Frequently asked questions
Are these all official holidays?
No. The calendar separates public holidays, official observances, religious festivals, organiser campaigns and cultural or commercial occasions. For office closures, use the relevant employer, government and regional holiday notification.
Why do some 2027 festival dates differ across calendars?
Location, religious tradition, lunar timing and the purpose of a calendar can change the date shown. A central-government holiday date can differ from a local celebration or ritual calendar. Keep the source and region attached to the date rather than treating one date as universal.
Is Mother's Day the same worldwide?
No. The May date here uses the US second-Sunday rule. Other countries observe Mother's Day on different dates. Check your audience before reusing a campaign across markets.
Can I use this as a Google Sheets social media calendar?
Yes. Import the Excel or CSV file into Google Sheets and check the imported dates and controls. The downloadable workbook is editable; no Google account access or scheduling integration is included.
Do I need to subscribe to get the templates?
Use your email to request the download. This request is for one-time resource access. It does not sign you up for marketing emails.
How often should I update the plan?
Review the next month before it starts and check the coming week for changed offers, availability, events or sensitive news. Recheck provisional dates closer to publication. Keep the source links with the plan so a correction is easy to trace.
