What this number means

Minutes are a fixed unit and months are not, so the conversion needs a convention before it can return a number at all. The one used here is the average Gregorian month. The US Naval Observatory gives the average year as 365.2425 days; a twelfth of that is 30.436875 days, and at 1,440 minutes a day that comes to exactly 43,829.1 minutes. The figure is a product, not a rounded decimal. The page opens on 12 months, which is 525,949.2 minutes. What that number is not is the length of any particular month. A 28-day February holds 40,320 minutes, a 30-day month 43,200 and a 31-day month 44,640, so the average sits among them and matches none of them. That is the limitation worth carrying away: for the exact span between two given dates, count days rather than average months.

An average month, not a calendar month

43,829.1 minutes is a twelfth of the average Gregorian year, so it matches no single month exactly. A 28-day February runs 40,320 minutes and a 31-day July 44,640.

For an exact span, count days

The average fits no particular month. For an exact span between two dates, count days instead.

The figure is exact, not rounded

43,829.1 is 365.2425 × 120, so the constant is a product rather than a rounded decimal. The US Naval Observatory gives the average Gregorian year as 365.2425 days.

It runs both ways

Enter minutes instead of months and the calculator solves the same equation the other way. 525,949.2 minutes come back as 12 months.

Commonly misread

A month is 30 days, so it holds 30 × 1,440 = 43,200 minutes.

That would only be right for four months of the year. The average month is 30.436875 days, because the year is not 360 days long.

43,829.1 minutes is how long a given month lasts.

It is an average. A 28-day February has 40,320 minutes, a 30-day month 43,200 and a 31-day month 44,640.

Going from minutes back to months needs a second calculator.

The same equation solves the other way — enter the minutes and read the months. 525,949.2 minutes come back as 12.

Questions

How many minutes are in a month?

43,829.1 on average. The figure is a twelfth of the average Gregorian year, which the US Naval Observatory gives as 365.2425 days.

Why not 30 days times 1,440?

That would be 43,200 minutes and would only be right for four months of the year. The average month is 30.436875 days because the year is not 360 days long.

How many minutes are in a calendar month?

A 28-day February has 40,320 minutes, a 30-day month 43,200 and a 31-day month 44,640. This calculator returns the average, so it does not match any single month exactly.

Can I convert minutes back into months?

Yes — enter the minutes and the calculator solves the same equation the other way. 525,949.2 minutes come back as 12 months.
