Leap years starting on Tuesday share this characteristic.
In the (currently used) Gregorian calendar, alongside Sunday, Monday, Friday or Saturday, the fourteen types of year (seven common, seven leap) repeat in a 400-year cycle (20871 weeks).
Forty-three common years per cycle or exactly 10.75% start on a Wednesday.
In the now-obsolete Julian calendar, the fourteen types of year (seven common, seven leap) repeat in a 28-year cycle (1461 weeks).
This sequence occurs exactly once within a cycle, and every common letter thrice.
