How many days is 360 months?

Answer 1

Although a "month" is not a fixed number of days, 360 months is 30 years, so in Julian years of 365.25 days it is 10957.5 days.

Depending on whether the 30 years included 7 or 8 leap years, it would be either 10,957 or 10,958 calendar days.

Answer 2

360 days is about 11.8 months, 5 days (and a fraction) less than a year.

If we were to use 30 days as an average month, rather then 30.4 days, then we would say that 360 days was 12 months, while it is obviously somewhat less than 12 months.
