How to Use This Calculator
Enter month and year
Specify the month (1–12) and year to generate the exact calendar layout, including the starting weekday.
Navigate quickly
Use Previous/Next buttons to move across months without typing. Great for scheduling multi-month projects.
Use the grid for planning
Copy the calendar into documents or use the weekday/weekend counts to calculate workdays, vacations, or billing cycles.
Formula
Days in Month = Date(Y, M + 1, 0).getDate()
First Day = Date(Y, M, 1).getDay()
Calendar Rows = Iterate weeks × weekdays filling day numbers
Example: February 2028 → 29 days, starts on Tuesday, ends on Tuesday, 20 weekdays, 9 weekend days (leap year).
