About this digital tool
The day of the week calculator tells you which day any date falls on: Monday, Tuesday, Wednesday, Thursday, Friday, Saturday or Sunday. Choose the date and the result appears instantly, for past, present and future dates.
The day is calculated with the Gregorian calendar, taking leap years into account. It is used to find out which day a birthday or a historical event fell on, which day a holiday will land, a payment deadline or the day of a meeting. To count how many days remain until an event, use the day counter, and to find a new date after some days, use the add-days calculator.
How to use
- Open the day of the week calculator.
- Enter or choose the date you are interested in in the date field.
- See the day of the week that appears instantly as the result.
- Change the date to check other dates.
