About this game

Step into the Leap Bureau, where damaged calendars, missing dates, and broken archive records are waiting for a careful investigator.

Leap Bureau Calendar Logic is a focused offline puzzle game built around the hidden patterns of the Gregorian calendar. Audit year files, decide whether February has 28 or 29 days, trace weekday shifts, and deliver date records to the correct destination.
