About the year and the month
A year here is the average Gregorian year of 365.2425 days, which includes leap years. A common year has 365 days and a leap year has 366.
A month in this converter is the average Gregorian month of 30.436875 days (365.2425 days divided by 12). Real months have 28 to 31 days, so a conversion to days is an average rather than a calendar count.
One year is 12 times the size of one month, so it takes fewer years than months to express the same amount.
