**According to conventional timekeeping, 12 noon is written as PM so 12 pm is noon.**

The 12-hour clock is a system of time in which the day is divided into two periods, lasting 12 hours each. These periods are called AM (ante meridiem) and PM (post meridiem). Noon is the transition point between the two periods and is usually denoted by 12 pm. In the 12-hour clock system, the day begins at midnight and ends at noon. For this reason, noon is considered the start of the PM period.

However, it is worth noting that there are some exceptions to this rule. In certain cases, 12 noon may be written as AM to avoid confusion. For example, if an event is scheduled to take place at 12 noon on a 24-hour clock, it may be listed as 12 am on a 12-hour clock to prevent ambiguity. Ultimately, whether 12 noon is written as AM or PM depends on the context in which it is used.

**How do you write 12:00 noon?**

**It is preferable to as 12 pm or 12 noon. **

When writing the time as 12:00, it is ambiguous as to whether you mean 12:00 am or 12:00 pm. Therefore, to avoid confusion, it is best to write 12 pm or 12 noon.

**What is 12 noon in the 24-hour clock?**

**12 noon on the 24-hour clock is 12:00. This is the same as 12:00 pm on the 12-hour clock.**

The 24-hour clock is a way of telling the time in which the day is divided into 24 hours, starting at midnight and ending at the following midnight. The hour hand on a 24-hour clock makes one complete rotation, covering all 24 hours, in one day. As a result, 12 noon on a 24-hour clock is simply written as “12:00” or “00:00.”

**Is noon 30 AM or PM?**

**Noon 30 or 12:30 is “pm”, not “am”. **

Noon is 12 o’clock. 30 minutes after noon is 12:30, which would be written as 12:30 pm. Noon 30 would therefore be read as “12:30 pm.”
