How to convert Months to Days

Time conversion spans tiny durations in seconds to long spans in weeks, months, and years. Months and years use the astronomical average: a year is 31,556,952 seconds (365.2425 days) and a month is one twelfth of that.

Seconds, minutes, hours, days, and weeks are exact multiples of each other (60 s = 1 min, 24 h = 1 day, 7 d = 1 wk). Months and years use average values so results stay consistent regardless of the calendar.

Formula

mo × 30.436875 = d

Multiply your months value by 30.436875 to get days. For the reverse, divide by the same factor.
