Question

What hour is 1 o clock?

Answer 1

1 o'clock refers to the time of 1:00, either 1:00 AM (in the early morning) or 1:00 PM (in the afternoon/evening). The distinction between AM and PM depends on context:

• 1:00 AM is one hour after midnight.
• 1:00 PM is one hour after noon.

In a 12-hour clock system, "o'clock" specifies the exact hour (e.g., 1 o'clock means the hour hand points directly at 1).

In a 24-hour format, this translates to 01:00 (AM) or 13:00 (PM). Without additional context, 1 o'clock is ambiguous but generally understood based on daily routines (e.g., meetings at 1 PM are more common than 1 AM).
