Day of the Week

Find which weekday any date falls on, for as many dates as you paste in.

Good to know

How should I write a date?

Use year-month-day, such as 2026-09-05, to avoid confusing the day and month.

What does a blank comparison date mean?

The comparison uses today when its second date is empty.

Are the years and months exact?

The years-and-months breakdown is approximate. Use the elapsed whole days, hours or minutes when you need a duration.
