What Does AM Mean in Time?

The most common meaning of AM is Ante Meridiem, a Latin phrase that means before midday or before noon.

The 12-hour clock divides the day into two periods:

• AM: 12:00 midnight to 11:59 in the morning
• PM: 12:00 noon to 11:59 at night

Examples

• 6:00 AM = Six o’clock in the morning
• 8:30 AM = Half past eight in the morning
• 11:45 AM = Quarter to noon

This system is widely used in countries like the United States, Canada, Australia, and several others.

Why Is It Called Ante Meridiem?

The abbreviation AM comes from Latin.

• Ante means before.
• Meridiem means midday or noon.

Together, Ante Meridiem literally translates to before noon.

The opposite abbreviation is PM, which stands for Post Meridiem, meaning after noon.

What Does 12:00 AM Mean?

One of the biggest sources of confusion is midnight.

Here’s the correct interpretation:

• 12:00 AM = Midnight
• 12:00 PM = Noon

Many people mistakenly think the opposite, so it’s always helpful to double-check appointments and schedules.

AM vs PM: What’s the Difference?

AM	PM
