How Many Hours Are in a Month?

The number of hours in a month depends on how many days that month has. Here is the breakdown:

Month TypeDaysHours
February (common year)28672
February (leap year)29696
30-day months (Apr, Jun, Sep, Nov)30720
31-day months (Jan, Mar, May, Jul, Aug, Oct, Dec)31744

Formula: Hours = Days in Month x 24

Working Hours vs. Total Hours

For payroll and project estimation, the distinction between total hours and working hours is critical. A 31-day month has 744 total hours, but typically only 160-184 working hours (8 hours x ~21 weekdays). The exact working hours depend on how weekends and holidays fall in that specific month. Use the "Work hours only" toggle to see the exact count for any month/year combination.

Common Use Cases

Knowing the exact hours in a month is essential for payroll calculations (hourly employees), project timeline estimates, server uptime calculations, subscription billing (monthly quotas), energy consumption tracking, and freelance billing. The "Generic" mode lets you quickly compute hours for any number of days without selecting a specific month.
