How the Time Converter works
One day is 0.0328548841 months here, one over the average month of 30.436875 days (the Gregorian year of 365.2425 days divided by twelve). Every real month is 28 to 31 days, so this converts days into average months, which is a useful estimate and not a date.
Worked through: 60 day x 0.0328548841 = 1.97129 month.
Going the other way, one month is 30.436875 days.
For mental arithmetic: Divide by 30.44, or by 30 if you are matching a 30/360 contract.
Finance sidesteps the problem by decree. Many bonds and loans count interest on a 30/360 basis, where every month is treated as exactly 30 days and every year as 360, so 90 days is three months by construction and a month's interest is the same in February as in March. Under that convention a day is 1/30 of a month; under the calendar average it is 1/30.44, and over 180 days the two disagree by about a tenth of a month. When a contract, a warranty or a notice period is written in months, the calendar decides it rather than either average: 180 days from a given date and six months from it usually land on different days.
Precision is worth matching to the input. A measurement given as 7 day carries one or two significant figures, and reporting its conversion to six implies a precision the original never had.
