What is a social media holiday calendar?
A social media holiday calendar is a curated list of international observances, national holidays and cultural moments that content creators and marketing teams use to plan timely, relevant posts. Rather than reacting to dates as they arrive, a holiday calendar lets you prepare content weeks ahead — so you show up with intention, not improvisation.
This calendar covers two distinct datasets: international observances used by global marketing teams, and Türkiye's official national calendar including public holidays, religious festivals and national commemoration days.
International vs. Türkiye calendar
The International calendar includes UN-designated days, WHO observances, major cultural events and widely-observed commercial moments like Black Friday and Valentine's Day. These dates are relevant for brands addressing global or Western-leaning audiences.
The Türkiye calendar includes every official public holiday confirmed by the Turkish government for 2026, religious holidays (Eid al-Fitr, Eid al-Adha) based on the 1447 AH lunar calendar, national commemoration days like Çanakkale Day and November 10, and culturally significant observances. These dates are essential for any brand communicating with Turkish audiences.
How to use this calendar for content planning
Start by identifying the dates most relevant to your brand and audience — focus on a handful of high-fit dates rather than trying to post on every occasion. Plan your content 2–4 weeks ahead: write captions, prepare visuals, and schedule posts in advance.
Not every holiday is right for every brand. Choose dates where you can add genuine value: share expertise, celebrate your team, or connect your work to the moment. Avoid posting just to be seen on a date. The marketing notes on each event in this calendar help you decide whether a day is worth engaging with and how.
A note on date accuracy
Türkiye's official public holidays are sourced from the Turkish Presidency's official calendar. Islamic holidays (Eid al-Fitr, Eid al-Adha and their eves) are calculated based on the 1447 AH lunar calendar; the Turkish Directorate of Religious Affairs (Diyanet) announces confirmed dates — slight variation is possible. International dates follow UN, WHO and UNESCO official observance calendars, with US federal holidays confirmed for 2026.

Questions about Türkiye's national holidays, religious observances and official calendar.
What is a social media holiday calendar?
A social media holiday calendar is a curated list of international observances, national holidays and cultural moments. Content creators and marketing teams use it to plan posts in advance around dates their audience cares about — instead of scrambling to react when a holiday arrives.
What international observances are included?
The international calendar includes UN-designated days (World Health Day, World Environment Day, International Women's Day), WHO observances, UNESCO days, major commercial moments (Black Friday, Valentine's Day, Mother's Day) and widely-observed cultural events. Every entry has a source — UN, WHO, UNESCO or an established international body — and a marketing note explaining how brands engage with it.
Which are the most important dates for social media in 2026?
High-engagement dates for most brands: International Women's Day (Mar 8), Earth Day (Apr 22), World Mental Health Day (Oct 10), and commercial moments like Valentine's Day (Feb 14), Black Friday (Nov 27) and Cyber Monday (Nov 30). The right dates depend entirely on your audience and industry — use the category filters in the calendar to find the days your brand can speak to authentically.
How do I pick the right dates for my brand?
Pick 6–10 dates per quarter that are genuinely relevant to your brand, audience and industry. Avoid posting on every occasion — it dilutes the impact and can come across as opportunistic on sensitive days. Read the marketing note on each event before deciding whether to engage: some awareness days call for genuine action, not just a graphic. Dates where you can add real value — share expertise, celebrate your team, or connect your work to the moment — are worth prioritising.
Are the international dates accurate and verified?
Yes. International dates follow UN, WHO and UNESCO official observance calendars. US federal holidays are confirmed for 2026. Each event in the calendar shows its source. Fixed dates (International Women's Day is always March 8) are exact; floating dates like Thanksgiving follow their established rules for 2026.

Which Türkiye national holidays are in 2026?
Türkiye's 2026 official public holidays: New Year's Day (Jan 1), Eid al-Fitr / Ramazan Bayramı (Mar 20–22), National Sovereignty and Children's Day (Apr 23), Labour Day (May 1), Atatürk Youth and Sports Day (May 19), Eid al-Adha / Kurban Bayramı (May 27–30), Democracy and National Unity Day (Jul 15), Victory Day (Aug 30), and Republic Day (Oct 29). Islamic holiday dates are based on 1447 AH lunar calendar calculations.
When is Eid al-Fitr (Ramazan Bayramı) 2026?
Eid al-Fitr (Ramazan Bayramı) 2026 in Türkiye is expected to fall on March 20–22, 2026, with the eve (Arife) on March 19. This is based on 1447 AH astronomical calculations. The Turkish Directorate of Religious Affairs (Diyanet) announces official confirmed dates; slight variation is possible depending on moon sighting.
When is Eid al-Adha (Kurban Bayramı) 2026?
Eid al-Adha (Kurban Bayramı) 2026 in Türkiye is expected to fall on May 27–30, 2026, with the eve (Arife) on May 26. These four days are official public holidays. Dates are based on 1447 AH calculations and subject to confirmation by the Diyanet.
Is November 10 a public holiday in Türkiye?
No. November 10 — the anniversary of Atatürk's passing — is a national commemoration day, not an official public holiday. Offices and businesses remain open. However, it is observed across Türkiye with a minute of silence at 09:05 and is one of the most significant dates in the Turkish national calendar. Brands communicating with Turkish audiences should treat it with appropriate solemnity.
How should I use Turkish holidays for content planning?
National holidays like Republic Day (Oct 29) and Children's Day (Apr 23) are major content moments for brands in Türkiye — high engagement, well-understood themes. Religious holidays (Eid al-Fitr, Eid al-Adha) call for warmth and respect, not commercial promotion. Commemoration days like November 10 or Çanakkale Day (Mar 18) require a respectful, understated tone. Plan your content 2–4 weeks ahead; visuals and captions for official holidays often need internal approval.
Are the Turkish holiday dates accurate?
Official public holidays are sourced from the Turkish Presidency's official calendar and confirmed for 2026. Islamic holidays (Eid al-Fitr, Eid al-Adha and their eves) are calculated from the 1447 AH lunar calendar and cross-referenced with typical Diyanet announcements. The Diyanet publishes confirmed dates closer to each holiday — slight variation is possible. All other national and commemoration days have fixed calendar positions.
