Six months of 29 days and six with 30 days, plus 11 days of the leap years. (29 days × 6 months + 30 days × 6 months) × 30 years + 11 leap days = 10,631 days and 10,631 / 360 = 29.53056 (360 is number of months in 30 years).

The leap year problem (also known as the leap year bug or the leap day bug) is a problem for both digital (computer-related) and non-digital documentation and data storage situations which results from errors in the calculation of which years are leap years, or from manipulating dates without regard to the difference between leap years and common years.
The best known of these is the Tabular Islamic calendar: in brief, it has a 30-year cycle with 11 leap years of 355 days and 19 years of 354 days. In the long term, it is accurate to one day in about 2,500 solar years or 2,570 lunar years. It also deviates from observation by up to about one or two days in the short term.
A leap year (also known as an intercalary year or bissextile year) is a calendar year that contains an additional day (or, in the case of a lunisolar calendar, a month) compared to a common year. The 366th day (or 13th month) is added to keep the calendar year synchronised with the astronomical year or seasonal year . [ 1 ]

A solar calendar year has 365 days (366 days in leap years).A lunar calendar year has 12 lunar months which alternate between 30 and 29 days for a total of 354 days (in leap years, one of the lunar months has a day added; since a lunar year lasts a little over 354 + 1 / 3 days, a leap year arises every second or third year rather than every fourth.)
