"Ante meridiem" (often written as 'a.m.') refers to the period from midnight to noon. It's a Latin phrase that literally means "before midday." It signifies the time before the sun reaches its highest point. Think of it as the first half of the day. βοΈ It's usually associated with morning activities. Unlike post meridiem (p.m.), it represents the hours when the sun is rising. It's a formal way to describe the time between midnight and noon.
