Figuring out the Day of the Week for April eighth, 2025
To use Zeller’s congruence, we have to perceive the system: h = (q + [(13(m+1))/5] + Ok + [K/4] + [J/4]
2J) mod 7, the place
* h is the day of the week (0 = Saturday, 1 = Sunday, 2 = Monday, …, 6 = Friday)
qis the day of the monthmis the month (3 = March, 4 = April, …, 12 = December; January and February are counted as months 13 and 14 of the earlier yr)Okis the yr of the century (yr % 100)Jis the zero-based century (yr / 100)
For April eighth, 2025:* q = 8
m = 4Ok = 25J = 20
Substituting these values into Zeller’s congruence: h = (8 + [(13(4+1))/5] + 25 + [25/4] + [20/4] - 2*20) mod 7h = (8 + 13 + 25 + 6 + 5 - 40) mod 7h = 7 mod 7h = 0Due to this fact, April eighth, 2025, was a Saturday.

- 7 + 3), the day of the week will probably be shifted ahead by 3 days from Saturday.
For Might twenty third, 2025:* q = 23
m = 5Ok = 25J = 20
Making use of Zeller’s congruence: h = (23 + [(13(5+1))/5] + 25 + [25/4] + [20/4] - 2*20) mod 7h = (23 + 15 + 25 + 6 + 5 - 40) mod 7h = 24 mod 7h = 3Due to this fact, Might twenty third, 2025, was a Tuesday.
