Is the time 0900 considered to be pm or am time

It's a.m.

Just add 12 hours and get 2100 for the p.m. equivalent.

The time 0900 is commonly referred to as "9:00 AM" or simply "9:00" in a 12-hour clock format. This means it is in the morning or the ante meridiem (AM) portion of the day.

To determine whether a time is AM or PM, you can use the 12-hour clock system. In this system, the hours are divided into two cycles: AM (from midnight to noon) and PM (from noon to midnight).

To read 0900 in a 12-hour clock format, follow these steps:
1. Check if the hour is greater than or equal to 13. In this case, 0900 is less than 13, so it falls into the AM cycle.
2. If the hour is less than 12, you can simply read it as is. So, 0900 can be read as 9:00 AM.

In summary, 0900 is considered AM or morning time.
