Hexadecimal time

Hexadecimal time is a way of telling time using only 16 numbers instead of 12 or 24. In normal time, we count from 1 to 12 and then start over at 1. In hexadecimal time, we count from 0 to 9 and then use the letters A, B, C, D, E, and F to represent the numbers 10 to 15. This makes it easier for computers to work with time, because hexadecimal numbers are used in computer programming.

To read hexadecimal time, you just need to look at the numbers and letters on a clock. For example, if the clock said "B4:E2:C4," that means it is B4 (11) hours, E2 (226) minutes, and C4 (196) seconds past midnight.

It might seem confusing at first because you're used to counting in a different way, but with a little practice, you'll get the hang of it!
