4Die definisie van 'n skrikkeljaar is as volg: Dit is 'n skrikkeljaar indien die jaar deelbaar deur 4 is, soos 1980. Indien dit 'n eeu-jaar is, moet die jaar deelbaar deur 400 wees. 1200 was bv. 'n skrikkeljaar, maar nie 1300 nie. Bereken hoeveel skrikkeljare daar vanaf 1892 tot 2012, beide ingesluit, was.
The definition of a leap year is as follows: It is a leap year if the year is divisible by 4, such as 1980. If it is a century, the year must be divisible by 400. 1200 was e.g. a leap year, but not 1300. Calculate how many leap years there were from 1892 to 2012, both included.- A29
