Year (Y) 25 (last two digits of 2025)
Century (C) 20 (first two digits of 2025)
Month (M) 5 (May)

Zeller’s Formula h = (D + Math.floor((13 * (M + 1)) / 5) + Y + Math.floor(Y / 4) + Math.floor(C / 4) – 2 * C) % 7
Adjusted Month and Year M = 3 (adjusted for Zeller’s), Y = 25
Calculation h = (30 + Math.floor((13 * (3 + 1)) / 5) + 25 + Math.floor(25 / 4) + Math.floor(20 / 4) – 2 * 20) % 7
Intermediate Steps h = (30 + 10 + 25 + 6 + 5 – 40) % 7 = 36 % 7 = 1
Result (h) 1 (corresponds to Friday: 0=Saturday, 1=Sunday, …, 6=Friday)
