The spelling of the word "post meridians" may seem confusing, but it can be broken down using the International Phonetic Alphabet (IPA). "Post" is pronounced as /pəʊst/, while "meridians" is pronounced as /mɛˈrɪdɪənz/. The word refers to the time after noon, and is often used in reference to train schedules or medical records.

"Post meridians" refers to a term used to identify a specific geographical location or time zone that is situated west of the Prime Meridian. The Prime Meridian, or Greenwich Meridian, is an imaginary line that runs from the North Pole to the South Pole, passing through Greenwich, London. It serves as the global reference for measuring longitude and is designated as 0 degrees.
The term "post meridians" is formed by combining the Latin prefix "post," which means "after" or "behind," with the word "meridians," referring to the lines of longitude on the Earth's surface. It signifies regions or places that occur after or west of the Prime Meridian.
When referring to time zones, "post meridians" correspond to those areas located to the west of the Prime Meridian, often referred to as Western or Negative hours. As one moves further west from the Prime Meridian, each successive time zone is usually designated as one hour earlier in relation to Coordinated Universal Time (UTC). For instance, if a time zone is denoted as UTC -3, it signifies that it is three hours behind Coordinated Universal Time and lies to the west of the Prime Meridian.
In summary, "post meridians" pertain to regions, time zones, or areas that are situated westwards or behind the Prime Meridian, signifying positions with negative time differences relative to Coordinated Universal Time.
The phrase "post meridians" is not a commonly used term. However, if you refer to "post meridiem", it is a Latin phrase that means "after midday" or "after noon". The word "post" means "after", and "meridiem" is derived from the Latin word "meridies", which means "midday". When combined, "post meridiem" refers to the time after 12 o'clock noon.
