Time And Calendar 2025: A Comprehensive Overview - Calendar 2025 August Month

The year 2025 is a common year starting on Wednesday of the Gregorian calendar. It is the 2025th year of the Common Era (CE) and Anno Domini (AD) designations, the 25th year of the 3rd millennium and the 21st century, and the 6th year of the 2020s decade.

Calculating the Day of the Week

To determine the day of the week for any date, you can use the Zeller congruence:

h = (q + (26 * m - 2) - 2 * c + y + (y / 4) + (c / 4)) mod 7

where:

  • h is the day of the week (0 = Sunday, 1 = Monday, …, 6 = Saturday)
  • q is the day of the month (1-31)
  • m is the month (3 = March, 4 = April, …, 12 = December; January and February are counted as months 13 and 14 of the previous year)
  • y is the year (e.g., 2025)
  • c is the century (e.g., 20 for the 20th century)

Applying the Zeller Congruence

For the year 2025, we have:

  • q = 1 (January 1st)
  • m = 1 (January)
  • y = 2025
  • c = 20

Plugging these values into the Zeller congruence, we get:

h = (1 + (26 * 1 - 2) - 2 * 20 + 2025 + (2025 / 4) + (20 / 4)) mod 7
h = (1 + 24 - 40 + 2025 + 506 + 5) mod 7
h = 2531 mod 7
h = 3

Therefore, January 1st, 2025, is a Wednesday. Since 2025 is a common year with 365 days, all other dates in the year will occur on the same day of the week as January 1st.
