Day of the Week Finder

About this tool

Pick any date — past, present, or years into the future — and instantly see what day of the week it falls on, plus how far away it is from today. Handy for settling "what day was that?" questions or checking a future date before booking something.

Frequently asked questions

How far back or forward does this work?

Any date your browser's date picker allows — typically a very wide range of years in both directions, using the standard Gregorian calendar.

Does this account for the switch from the Julian calendar?

No — it calculates using the modern Gregorian calendar throughout, which is accurate for any date from 1582 onward (when the Gregorian calendar was introduced) but not for earlier historical dates in regions that used the Julian calendar.

What does "relative to today" mean?

It shows roughly how many days, weeks, or years separate the chosen date from today, and whether it's in the past or future.
