In a single calendar year there are 365 days, but every four years a leap year occurs and one day is added to make 366 days for that year. To account for this extra day you must figure out how many times a leap year would occur in 60 years. 60 divided by 4 is 15, so there will be 15 extra days. To figure out how many days are in 60 years, first multiply 60 by 365, which equals 21,900 days and then add the 15 leap days. 21,900 days + 15 days = 21,915 days. There are 21,915 days in 60 years.

How can the number of minutes in 30 days be calculated by?
To calculate the number of minutes in 30 days, multiply the number of minutes in an hour (60) by the number of hours in a day (24) and then multiply that result by the number of days (30). Therefore, 60 (minutes per hour) x 24 (hours per day) x 30 (days) = 43,200 minutes in 30 days.

How many seconds are in a month?
On average, a month has about 2,592,000 seconds (30 days x 24 hours x 60 minutes x 60 seconds).
How many milliseconds are there in a week?
60 seconds in one minute multiplied by 60 minutes in one hour multiplied by 24 hours in one day multiplied by 7 days in one week multiplied by 1000 milliseconds in one second = 60 x 60 x 24 x 7 x 1000 = 604800000 milliseconds.
