Date Calculation Formula
$$\text{Day of Week} = \left( y + \left\lfloor \frac{y}{4} \right\rfloor – \left\lfloor \frac{y}{100} \right\rfloor + \left\lfloor \frac{y}{400} \right\rfloor + \left\lfloor \frac{31m}{12} \right\rfloor + d \right) \mod 7$$
Where:
- $$y$$ = year
- $$m$$ = month (with January and February treated as months 13 and 14 of the previous year)
- $$d$$ = day of the month
This formula helps determine the day of the week for any given date using Zeller’s congruence.
This tool uses date logic and Zeller’s congruence to calculate the day of the week for the first day of the month. It then maps all days to a classic 7-day calendar grid. Users can generate calendars for planning school terms, work schedules, or personal activities. You can print, save, or embed the calendar into a digital planner.
