One of the oldest gold mines in the province, the Kromdraai Gold Mine, is an interesting place to visit for anyone looking to learn more about Gautengâs gold rush history. Only a 40-minute drive north of Johannesburg, the Kromdraai Gold Mine is located in the scenic Cradle of Humankind World Heritage Site, one of the major tourist attractions in South Africa. Gold is central to the history of Gauteng and it was only as recently as 1886 that the city of Johannesburg was founded, mainly due to the vast amounts of gold to be found in the area.
4 centuries is 400 years and a leap year occurs every 4 years, therefore 100 leap years will occur in 4 centuries. 365*300 + 366*100 = 146100 days 1440 minutes in 1 day â¦1440*146100 = 210384000 minutes in 400 years.
A year is a leap year if it is divisible by 4, but century years are not leap years unless they are divisible by 400. So, the years 1700, 1800, and 1900 were not leap years, but the year 2000 was, which is why in a given 100 years, there are 24 leap years and 76 ordinary years. Why Do We Need Leap Years? The actual length of a year (the revolution of Earth around the Sun) is 365.2422 days. If we didn't have leap years, the seasons would shift about a quarter of a day every year, and after 100 years the seasons would be off by 25 days. The extra leap day adjusts this drift. it is divisible by 400.
