Formula Used in “Day of the Week Calculator”
The Day of the Week Calculator utilizes a mathematical formula known as Zeller’s Congruence to determine which day of the week a specific date falls on. Below is the standard formula:
h = (q + ⌊13(m + 1)/5⌋ + K + ⌊K/4⌋ + ⌊J/4⌋ – 2J) mod 7
Where:
Step-by-Step Breakdown of the Formula
- h: The result of the formula, where 0 = Saturday, 1 = Sunday, 2 = Monday, 3 = Tuesday, 4 = Wednesday, 5 = Thursday, and 6 = Friday.
- q: The day of the month (1 to 31).
- m: The month (3 = March, 4 = April, …, 12 = December; January and February are counted as months 13 and 14 of the previous year).
- K: The year of the century (year mod 100).
- J: The zero-based century (actually ⌊year/100⌋).
Calculation Process
- Identify the values of q, m, K, and J based on the date you want to calculate.
- Adjust the month and year if the date is in January or February.
- Substitute the identified values into Zeller’s formula.
- Perform the calculations step-by-step as per the formula.
- Execute the modulo operation (mod) to find the value of h.
- Interpret the result, relating h to the corresponding day of the week.
Example Calculation
Let’s calculate which day of the week September 22, 2023 falls on using Zeller’s Congruence.
Inputs
| Parameter | Value |
|---|---|
| Day of the Month (q) | 22 |
| Month (m) | 9 |
| Year of the Century (K) | 23 |
| Zero-based Century (J) | 20 |
Calculating Step-by-Step
Substituting our values into the formula, we have:
h = (22 + ⌊13(9 + 1)/5⌋ + 23 + ⌊23/4⌋ + ⌊20/4⌋ – 2(20)) mod 7
Calculating each component:
- ⌊13(10)/5⌋ = ⌊130/5⌋ = 26
- ⌊23/4⌋ = 5
- ⌊20/4⌋ = 5
Now substituting these values back into the equation:
h = (22 + 26 + 23 + 5 + 5 – 40) mod 7
Calculating this gives:
h = (41) mod 7 = 6
Result Interpretation
Since h = 6, September 22, 2023, is a Friday.
