Manual Method – How to Calculate the Day Yourself
If you love math or want to know the logic behind the calculation, you can use Zeller’s Congruence formula. It helps compute the day of the week manually for any date in the Gregorian calendar.
Formula: h = (q + ⌊(13(m+1))/5⌋ + K + ⌊K/4⌋ + ⌊J/4⌋ - 2J) mod 7
- q = day of month
- m = month number (March = 3, …, January = 13, February = 14)
- K = year of century (year mod 100)
- J = century (year / 100)
For example, July 4, 1776 gives h = 5, meaning Thursday — exactly what our Date to Day Converter shows instantly!
