In a year there are 12 months.
There are also 365 days in a year and always 12 months in each year.
In 10 years there are 120 months and 3,650 days.
In 5 years there are 60 months and 1,825 days.
And in a year there are 525,600 minutes.
Also it is easiest to determine and work with the total number of days in a year, which is 365.
To arrive at the answer, all you need to do is to multiply the number of minutes in a single hour with the total number of hours in a day.
i.e. 1440 (minutes) x 365 = 525,600 minutes (in a year).
On Earth, a solar day is around 24 hours. However, Earth's orbit is elliptical, meaning it's not a perfect circle.
That means some solar days on Earth are a few minutes longer than 24 hours and some are a few minutes shorter.
On Earth, a sidereal day is almost exactly 23 hours and 56 minutes.
There would be approximately 52560000 minutes in hundred years and 40471200 minutes in 77 years.
1 min =60 sec. 1 Day=1440 min.
