Am i too old to find someone

However, the 12-hour format, including am and pm, is officially used in a number of countries, including the United States, Canada (except Qubec), Australia, New Zealand, and the Philippines.

Another source of confusion is the lack of a date designator in the 12-hour system, which makes it impossible to logically identify a correct moment in time when only a date and 12:00am (midnight) are provided.

However, most digital clocks and a majority of sources, including timeanddate.com, designate midnight as 12am and noon as 12pm. Although the precise moment of noon falls in neither category, the hour succeeding it, from 12:00:01 to 12:59:59, is clearly after noon (pm).

The main weakness of the 12-hour system is widespread confusion about which abbreviation should be used for noon and midnight. Neither moment can logically be identified as before noon (am) or after noon (pm).
