Question: is am day or night?
Answer: AM stands in short for Ante Meridiem, de latin name for “Before Midday” or “Before Noon”. An example: 10.00 a.m. is 10 o-clock in the morning. With a 24 hour time this is 10:00. PM stands in short for Post Meridiem, de latin name for “After Midday” or “After Noon”.
