Understanding festival dates around the world

Many Hindu and Vedic festival dates depend on lunar day, nakshatra, solar movement, sunrise or a specific observance window. Because sunrise and local clock time vary by place, the civil date can differ between cities. A schedule calculated for Delhi should not automatically be copied for Dubai, London or Toronto.

Use the location shown on the page, confirm the year and read the observance notes for the tradition you follow. Communities may apply different regional calendars, authorities or ritual conventions. The Celestial presents calendar information for planning and education while encouraging users to confirm important observances with their local community.

How to verify a festival date

Set the location

Use the city where the observance will take place, not a default country. Sunrise-based boundaries require local coordinates and time-zone rules.

Check the governing element

Identify whether the observance depends on tithi, nakshatra, solar ingress, moonrise, sunrise or another stated rule.

Respect regional practice

When traditions differ, the page should explain the calculation instead of claiming that one worldwide civil date is universal.

Common questions

Why does a festival appear on two different dates online?
The sites may use different locations, time zones, calendar rules or community conventions. Compare the stated inputs before deciding which date applies to you.
Are the listings limited to Indian cities?
They should not be. Location-aware calculations can serve users worldwide, including the Middle East, as long as the selected city and time-zone data are correct.
