On average, a month contains 730.5 hours — but a specific calendar month ranges from 672 hours (28-day February) to 744 hours (any 31-day month). Use the calculator to convert hours to months, months to hours, or get the working-hours total for any schedule.

A month does not have a fixed length — calendar months range from 28 to 31 days. To get a single, useful answer the calculator uses the average month: 365.25 days per year (which accounts for leap years) divided by 12 months gives 30.4375 days per month, which is 730.5 hours per month. Converting the other way, one hour equals about 0.001369 months.
For an exact answer for a specific month, choose Specific calendar month and pick the month and year — the calculator multiplies the actual number of days (28, 29, 30 or 31) by 24. The 30-day month mode is a simpler business approximation that treats every month as 30 days × 24 = 720 hours.
The working-hours mode multiplies your daily working hours by your working days per week, then by the average number of weeks in a month (4.345 = 30.4375 ÷ 7). At 8 hours a day, 5 days a week, that's about 173.8 working hours per month.
