How many seconds are in 9 months?

Answer 1

1 hour is 3600 seconds; 1 day is 24 hours; 24x3600= 86,400, i.e. 1 day is 86,400 seconds. Let's suppose it is a 30-day month, you have to multiply 30x86,400=2,592,000.

so, the answer is: there are 2,592, 000 seconds in 1 month, and 9x2,592,000=

23, 328, 000 seconds in 9 months. You have to add 86,400 as many times as many 31-day months you have, of course you have to subtract some days if you have February in the list.
