FAQ
How do you find the weekday?
We use a well-known algorithm that maps a calendar date to a weekday (no time zone required). It correctly handles leap years and century rules.
Does time of day or location matter?
For most modern dates, the weekday of your birth date is the same worldwide. Time zones affect the clock time, not the local calendar date you were born on.
Which calendar do you use?
Gregorian calendar (the one used by most countries today). Historical dates before adoption can be tricky; consult specialist resources if needed.
Why does the weekday of birth matter?
Knowing what weekday you were born on is fun trivia — but it also has cultural meaning. In some traditions, the day of the week you were born is believed to influence personality traits. In astrology and numerology, birth weekdays are sometimes used alongside other factors to interpret character.
It’s also practical: maybe you want to know if you were born on a weekend, or check whether a family member’s birthday falls on the same weekday as yours.
Examples
If you were born on 2000-01-01, this calculator shows you were born on a Saturday.
If you were born on 1990-12-25, your birth weekday was a Tuesday.
