Day of the week finder
What day was India's Independence Day in 1947? Which day of the week were you born on? Will your next birthday fall on a weekend? This day of the week finder answers questions like these for any date from 1600 to 2999. It also shows the step-by-step Zeller's congruence calculation — a favourite of reasoning sections in competitive exams — and the weekday of the same date over the next few years.
How to use it
- Pick or type a date.
- Read the weekday, how long ago or ahead it is, and the working.
Example
15 August 1947 was a Friday. 26 January 1950, when the Constitution came into force, was a Thursday. In 2026, 15 August falls on a Saturday. Find your exact age with theage calculator, and the ISO week of a date with theweek number calculator.
Frequently asked questions
How can I find the day of the week for any date?
Enter the date and the finder shows the weekday instantly — for past dates such as your birth date or historical events, and future dates like a wedding or exam day. It uses the Gregorian calendar, which India has used officially since 1752.
Can I work it out in my head?
Yes, with practice. Methods like Zeller’s congruence or the “Doomsday” rule let you calculate weekdays mentally. The working below shows Zeller’s formula step by step for the date you enter.
What day of the week was I born?
Enter your date of birth. The page also lists the weekday of your birthday in the next few years, so you can see when it next falls on a weekend.
Why does the same date fall one day later each year?
365 days is 52 weeks plus 1 day, so a date usually moves forward by one weekday each year — by two after 29 February in a leap year.
