How many months is 66 days?

Answer 1

It is 2 months and 5 or 6 days.

A month is not a set number of days, although the average is 30.42 days (based on a calendar year) and 30.44 (based on a Julian year of 365.25 days).

------------------------------------------------

The exact number of months depends upon which months those 66 days cover. Based on:

1 year = 12 months

1 year = 365.25 days

→ 12 months = 365.23 days

→ 1 month = 365.25/12 days on average.

→ 66 days = 66 ÷ 365.23/12 months

= 66 × 12/365.25 months

= 2 82/487 months (= 2 months 5⅛ days)

≈ 2.17 months

≈ 2 months 5.13 days

(So the original answer of 2 months 5 or 6 days is a good estimate.)
