Multiply 1461 by 5. 5 x 4 = 20. (Don't forget the leap years.)
The year has 365 day 366 in a leap year which happens every 4 years.
Since each hour has 60 minutes and each day has 24 hours and each year has 365.25 days, 4 years is equivalent to 2,103,840 minutes.
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 1440*146100 = 210384000 minutes in 400 years
4 years = 104.2989417989 fortnights.
there are 4 months a year that have 30 days; in four years that is 4 x 4 = 16 30 day months
That depends on whether they are common years, leap years, mean solar years, etc. On the Gregorian calendar, 4 consecutive years are usually (and on the Julian calendar always) 3 common (365-day) years and 1 leap year. That makes 1,461 days. There are 24 hours in a day and 3,600 seconds in an hour, for a total of 86,400 seconds in a day. Multiplying that by 1,461 gives 126,230,400 seconds in a typical 4-year period.
16 years is equivalent to 5,840 days when considering non-leap years.
There are: 4*20 = 80 years
Febuary has 28 days, except once in every 4 years, febuary has 29 days.
