how to ACTUALLY figure out world time because i personally think Ollie's method is wacky: subtract 12 from the hours. it's really that simple.

18:56 - 12:00 = 6:56 P.M.

Ollie 2024-07-26 21:49:42

for figuring out military time, just subtract the double digit numbers by 2 and get rid of the 1 in front.

For Example=
15:00
15-2=13
Get rid of the 1 in front,
3:00!

This site helps so much with school knowing how much longer is left in the period/school day! I do agree it needs a pm and am

Abha 2022-09-13 21:52:56

I don't like this site military time is way too confusing. they should add 2 options

Brad 2022-08-22 11:51:37

Don't Complain about AM/PM. Just add 12 to any time between Noon and Midnight. EX: 5:40 PM = 17:40. "Military Time" is far less confusing when used properly.

Aviva Tessorizse 2022-07-13 16:30:42

I agree, put am and pm. This will make it less confusing
