Calendar length—Use the standard number of days in months.
For example, January has 31 days. February has 28 in most years, but 29 in leap years. A year has 365 or 366 days. Quarters and halves are calculated based on the aggregate months, so quarters and halves will not have equal numbers of days.
Equal length—Have months consist of 30 days.
Calculated quarters and halves will have equal numbers of days. Years have 360 days.
Month — Enter the last month of the fiscal year.
