Editing Common year starting on Monday (section)

=== Gregorian calendar ===
In the (currently used) Gregorian calendar, along with [[Common year starting on Sunday|Sunday]], [[Common year starting on Wednesday|Wednesday]], [[Common year starting on Friday|Friday]] or [[Common year starting on Saturday|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 Monday. The 28-year sub-cycle only spans across century years divisible by 400, e.g. 1600, 2000, and 2400.
