Calculating the Day of the Week

To calculate the day of the week for a given date, we can use the Zeller's Congruence formula. The formula is as follows:

h = (q + [13(m+1)/5] + K + [K/4] + [J/4] - 2J) mod 7

Where: - h is the day of the week (0 = Saturday, 1 = Sunday, 2 = Monday, ..., 6 = Friday) - q is the day of the month - m is the month (3 = March, 4 = April, ..., 12 = December, 1 = January, 2 = February) - K is the year of the century (year % 100) - J is the zero-based century (year / 100)

Let's use this formula to calculate the day of the week for the given date.

Calculation

Given: - q = 31 - m = 3 - K = 23 (for the year 2023) - J = 20 (for the century 2000)

Substitute these values into the formula: h = (31 + [13(3+1)/5] + 23 + [23/4] + [20/4] - 2*20) mod 7

Calculating the values inside the brackets: h = (31 + [52/5] + 23 + 5 + 5 - 40) mod 7 h = (31 + 10 + 23 + 5 + 5 - 40) mod 7 h = (24) mod 7 h = 3

Result

Therefore, the day of the week for March 31, 2023, will be Thursday.
