How many minutes are in 28 years?

Answer 1

By multiplication, this would be 14,726,880 minutes.

There are 1440 minutes per day. There are 365 days in a year, so 525,600 minutes in a year. So 28 years would be 14,716,800 minutes, except that 28 years will have 7 leap years, so add 7 x 1440 for those 7 extra days [10,080 minutes].

You reach the same value by multiplying the minutes per day by 365.25 (the Julian year) and then by 28 years.

However, by the "SI year" of exactly 31556926 seconds, the number of minutes in 28 years (multiplied by 28 and divided by 60) would be 14,726,565.47 minutes in 28 years.
