About the Day of the Week Calculator
Every calendar date falls on one of seven weekdays. This calculator works out the weekday for any date, whether it's decades in the past or far in the future.
How it works: The calculator converts the calendar date into a day index (0 for Sunday through 6 for Saturday) using the standard proleptic Gregorian calendar.
Handy for confirming historical events, verifying birthdays, or planning recurring future dates.
