Day of the Week
What day of the week any past or future date falls on.
The day of the week calculator tells you which weekday any date falls on — past or future. Enter a date and it instantly shows the weekday, phrased in the right tense (“fell on”, “is”, or “will fall on”), along with a short historical fact for notable dates. Find out what day you were born, which day a holiday lands on this year, or the weekday of any date in history.

Frequently asked questions
What range of dates is supported?
You can enter dates far into the past or the future. The weekday is computed from the calendar date, so it works across centuries.
What day of the week was I born on?
Enter your date of birth and the tool shows the weekday it fell on, along with the full written date.
Why does the wording change?
The tense adapts to the date: past dates “fell on” a weekday, today “is” a weekday, and future dates “will fall on” one.
Where do the historical facts come from?
Selected dates carry a short fact about something notable that happened on that day of the year. Other dates show a neutral placeholder.
Is the weekday adjusted for time zones?
No. A calendar date maps to a single weekday, so the result is the same everywhere and does not depend on your time zone.
