Hours in different time periods

An hour usually means 60 minutes, and a minute is 60 seconds. We define a second based on scientific standards. There are 24 hours in a day. People tell time using either a 12-hour clock or a 24-hour clock.

12-hour clock

This clock shows time from 1 to 12. On most traditional clocks and watches, it might not say if it’s morning or evening. However, on digital displays, “AM” means “before midday,” and “PM” means “after noon.” Here, 12 AM is midnight and 12 PM is noon. Saying “midnight” or “12 noon” can help clear up any confusion about the time.

24-hour clock

This clock uses a 24-hour format, starting at midnight (00:00) and covering 24 hours to the next midnight. It avoids confusion, especially in professional settings like the military. Hours from 0 to 11 correspond to AM, and 12 to 23 are like PM in a 12-hour clock. This precise format is often called military time.
