Where:
- $$h$$ is the day of the week (0 = Saturday, 1 = Sunday, …, 6 = Friday)
- $$q$$ is the day of the month
- $$m$$ is the month (3 = March, 4 = April, …, 14 = February)
- $$K$$ is the year of the century (year % 100)
- $$J$$ is the zero-based century (year / 100)
Note: January and February are counted as months 13 and 14 of the previous year.
This calculator is useful for anyone needing to identify the weekday of historical, current, or future dates. For example, use it to verify which weekday your birthday fell on in a given year, check the date of a historical event, or plan for appointments and travel. The calculation is based on Zeller’s Congruence, a reliable formula used for calendar computations. It works for both Gregorian and Julian calendars (with adjustments).
