Perfect month

A perfect month or a rectangular month designates a month whose number of days is divisible by the number of days in a week and whose first day corresponds to the first day of the week.[1][2] This causes arrangement of days of the month to resemble a rectangle. In the Gregorian calendar, this arrangement can only occur for the month of February.

Constraints

To satisfy such an arrangement in the Gregorian calendar, the number of days in the month must be divisible by seven. Only the month of February of a common year can meet this constraint as the month has 28 days, a multiple of 7.[3]

In order for a February to be a perfect month, the month must start on the first day of the week (usually considered to be Sunday or Monday). For Sunday-first calendars, this means that the year must start on a Thursday. As for Monday-first calendars, the year must start on a Friday. It must also occur in a common year, as the phenomenon does not occur when February has 29 days.

Occurrence

The next perfect months will be February 2026 (Sunday-first) and February 2027 (Monday-first).

Attributes

The calendar arrangement brings together notions of harmony and organization.[5][6]
