To calculate the total number of seconds in the month of September, we need to consider the varying number of days in the month. September has 30 days, which is equivalent to 30 x 24 hours x 60 minutes x 60 seconds = 2,592,000 seconds.
60/24 = 2.5 days
24 days x 24 hours x 60 minutes x 60 seconds = 2,073,600
11 days = 11*24 hours = 11*24*60 minutes = 11*24*60*60 seconds = 950,400 seconds.
86,400 = 60 x 60 x 24
Divide the minutes by 60, to convert them to hours.Then divide the hours by 24, to convert to days.
565900/60/60/24 is 6.55 days
