The most common way to reconcile the two is to vary the number of days in the calendar year. In solar calendars, this is done by adding an extra day ("leap day" or "intercalary day") to a common year of 365 days, about once every four years, creating a leap year that has 366 days (Julian, Gregorian and Indian national calendars).
Ayyám-i-Há is a period of intercalary days in the Baháʼí calendar, when Baháʼís celebrate the Festival of Ayyám-i-Há. [2] The four or five days of this period are inserted between the last two months of the calendar (Mulk and ʻAláʼ). [3]
The number of the intercalary days is determined in advance to ensure that the year ends on the day before the next vernal equinox. This results in 4 or 5 intercalary days being added. These days are inserted between the 18th and 19th months, falling around the end of February in the Gregorian calendar.
His rule for leap years was a simple one: add a leap day every 4 years. This algorithm is close to reality: a Julian year lasts 365.25 days, a mean tropical year about 365.2422 days, a difference of only ≈ 11 1 / 4 min. [4] Consequently, even this Julian calendar drifts out of 'true' by about 3 days every 400 years.
The 23rd is ante diem vii kalendas Martias, the next day in a leap year is a.d. bis sextum kal. Mart., the next day is the regular a.d.vi kal. Mart., and so to the end of the month. For example, in 2024 (=GF), all days preceding the leap day corresponded to a common-year G calendar, and all days afterward corresponded to a common-year F calendar.

Every one of these calendars has a year of 365 days, which is occasionally extended by adding an extra day to form a leap year, a method called "intercalation", the inserted day being "intercalary". The Baháʼí calendar , another example of a solar calendar, always begins the year on the vernal equinox and sets its intercalary days so that ...
