Question

why do we use the 24- hour clock instead of 12- hour clock​

Answer 1

Answer:

Anyway, as near as I can tell, the 12-hour clock goes way back to ancient Mesopotamia and Egypt. The Egyptians used a 12-hour sundial to tell time during the daytime and a 12-hour water clock at night. ... Early mechanical clocks showed all 24 hours, but over time, clockmakers found the 12-hour system simpler and cheaper.

Answer 2

Answer:

because in 12 HR clock people confuse due to same number and in 24 HR clock the number continues after 12
