What the tool does

Give it any date and it tells you what day of the week that date falls on. It works for a date in the past, so you can find what day you were born, and for a date in the future, so you can see which day an event lands on. The full date and the weekday show together.

Why the weekday matters

Knowing the day of the week for a date helps with planning: whether a deadline falls on a weekend, which day a birthday will be next year, or what day a historical date was. The tool answers "what day of the week" in one step, giving the day of week for date and the weekday of date with no counting on your fingers.

The calendar it uses

The result follows the standard calendar used around the world today, the Gregorian calendar. For dates within the last few centuries this matches the day people actually used, which is what almost everyone needs.
