Seven country hubs to start, each with its own festival calendar and cultural context.

Why festival dates are hard to get right

Most sites copy last year's date and change the year. We don't.

Lunar calendars shift

Diwali, Holi, and Loy Krathong follow lunar months, so their Gregorian date moves every year — sometimes by a full month when a leap month is inserted.

Moveable feasts follow Easter

Mardi Gras and Rio Carnival are fixed relative to Ash Wednesday, which is calculated from Easter — itself set by a centuries-old lunar formula.

"Fixed" isn't always simple

Notting Hill Carnival is fixed to a day of the week (the August Bank Holiday Monday), not a day of the month — so the date still changes annually.

Frequently asked questions

How does Festivals.one verify dates?

Every date on this site is checked against the calendar rule that actually governs it — a lunar tithi, a moveable-feast calculation, or a fixed civic date — and cross-checked against multiple independent sources before publishing. Pages state the rule, not just the date, so you can see why it falls when it does.

Which countries does Festivals.one cover?

We're starting with India, the United States, the United Kingdom, Japan, Thailand, Spain, and Brazil, with deeper coverage and more countries planned as each hub matures.

Is Festivals.one just a holiday calendar?

No — public holiday calendars list dates. We cover festival history, cultural significance, how each is actually celebrated, and genuine regional variation, aimed at travelers and culturally curious readers rather than payroll departments.
