AM and PM Explained

Subject: Static GK (General Knowledge)

Book: General Time Knowledge

AM stands for “ante meridiem,” which translates to “before midday,” and PM stands for “post meridiem,” meaning “after midday.” This 12-hour clock convention divides the day into two blocks of 12 hours each, starting from midnight (12 AM) to noon (12 PM), then noon to midnight again. While many countries have shifted to a 24-hour standard, the AM/PM system remains deeply ingrained in daily life across North America and elsewhere. People often seek clarity on proper usage, especially regarding the confusing nature of midnight and noon. Understanding AM/PM can reduce scheduling errors and align your daily activities more reliably.
