Check a date without scanning a calendar
Use the weekday calculator for a past event, a future plan or a birthday. It reads the selected calendar date without converting it through your local time zone.
The result uses the Gregorian calendar. For historical dates from places that used another calendar at the time, that distinction matters.
How to use this tool
- Choose the day, month and year.
- Read the weekday result.
- Use the calendar generator if you need the surrounding month.
Example
1 January 2000 was a Saturday in the Gregorian calendar. The same date input gives that weekday regardless of your device time zone.
Common questions
Can I check a future date?
Yes. Enter the date you want to check. Use the week number tool if you also need its ISO week.
