The result also tells you whether the date falls on a Saturday or Sunday.
What does this tool do?
The weekday is fixed by the calendar, so a date far in the past or future has one correct answer. This calculator also shows the day of the year and whether the date lands on a weekend.
The Formula
Weekday = Gregorian calendar date counted in a repeating seven-day cycleFrequently Asked Questions
Can the weekday change with the time zone?
The date is read as a local calendar date, so the weekday label is fixed for that date. Only a different date would change it.
Why is Sunday both day 0 and day 7?
JavaScript numbers Sunday as 0 at the start of the week. The numeric option displays Monday as 1 through Sunday as 7 for a Monday-first convention.
