Important days are specific dates chosen by society to remember an idea, a person, an achievement, or a public-interest issue—and to spread awareness about it. Important Days 2026, Some dates commemorate major historical events (e.g., Independence, Republic, valour), while others highlight public awareness around health, environment, education, science, culture, and human rights. On these days, government bodies, schools–colleges, media, and citizen groups come together for campaigns, events, and discussions.
These dates have different origins. Many international/world days are declared by the United Nations (UN) and its agencies like WHO, UNESCO, UNEP, FAO, etc.; whereas national days arise from Government of India notifications, historic birth/death anniversaries, or institutional foundation days. Some days fall on a fixed date every year (e.g., 14 April, 21 June), while others follow moveable rules—for instance, Rare Disease Day is observed on the last day of February (29th in a leap year, otherwise 28th).
Keeping national and international tables separate helps in two ways: you clearly see India-centric heritage, services, and initiatives (Army/Navy/Air Force Days, Civil Services Day, National Technology/Science/Statistics Days), and you also get a consolidated view of global initiatives (World Health, Water, Environment, Education, Peace, Human Rights, etc.). Across the year, activities on these days strengthen participation, responsibility, and social sensitivity—that’s the real purpose of observing them.
Below, for 2026, the dates are arranged month-wise, first National (India) and then International/World for each month so the context is clean, simple, and useful.

This list has been prepared by the academic team at Doon Defence Dreamers (Best NDA Coaching in Dehradun). Our aim is not only to state “which date” but to explain “why it is observed.” Above, you’ll find month-wise tables—first National, then International—so reading and sharing stays easy.
FAQs
1) What’s the difference between National and International (World) days?
National days are tied to Indian authorities or institutions (e.g., Army Day, Civil Services Day), while International days are set by global bodies like the UN/WHO/UNESCO (e.g., World Water Day).
2) Do these days have yearly themes?
Yes. Most UN/International days announce a new theme each year. After publishing, update themes from official releases or press notes.
3) When is Rare Disease Day—28 or 29 February?
Always on the last day of February—29 in a leap year, otherwise 28.
4) Why keep separate month-wise tables (National/World)?
So India-specific dates are quick to scan, and global dates are clearly visible for the same month—making it easier to review, save, and update.
5) Can I use these tables for school/coaching activities?
Yes, with attribution. If any date/theme changes, recheck against the latest official sources before printing.
