However, the legal documents, schedules, and other interactions that require high precision time identification should follow the 24-hour format to avoid confusion with the denomination of noon and midnight. It could be used in conversations and informal communication only. With the ambiguity of 12-hour clock convention, many establishments require that this time representation should be scrapped altogether. Meanwhile, the fact that AM is alphabetically closer that PM should be the designation that it is before the midday. Considering that AM corresponds to the start of the day, knowing that A signifies the start of the alphabet could be a perfect point of reference for memorizing. However, there is a simple solution that does not even require to know the actual translation of the abbreviations (ante/post meridiem).ĪM - starts with the first letter of the alphabetA. How to memorize AM and PM?įor the people who just encountered the 12-hour convention, it might be difficult to memorize to what part of the day AM and PM refer to. The lack of consistent rules among all style guides is the primary factor why people could face the issue of how to write the time appropriately. Nevertheless, the most common rule in formal writing is to use uppercase AM/PM 1. Also, the use of the period between the letters (A.M./P.M.) might be acceptable. For instance, there could uppercase AM/PM or lowercase am/pm. Different style guides suggest different types of writing the abbreviation.

It is easier to say 6 PM rather than 18 hours. The most common argument in favor of using the 12-hour convention is easy pronunciation. The following countries utilize the 12-hour clock to denominate time: Namely, this tradition is peculiar to the English speaking states and territories which were part of the British Empire. Where AM and PM?ĭespite the ambiguity of the 12-hour time convention, it is used in many countries. Hence, it is highly ineffective to use only ‘midnight’ when indicating a date of event. Although technically, midnight implies AM, the lack of clarifications regarding whether it is 11:59 PM or 12:01 AM might be misleading and ambiguous. To avoid the confusion regarding denomination of noon and midnight, the convention refers to 12 AM as midnight and to 12 PM as noon. Namely, it is difficult to determine the starting point of the day cycle. One of the most common ambiguities of AM and PM was the confusion regarding the start of a day. Eventually, the decision to divide a day into two cycles which lasts 12 hours was influenced by the fact that the moon also had 12 cycles. Therefore, with the help of sundial clocks, ancient people were able to identify time only during a particular period of the day. In particular, people were able to measure time only using the sun. The tradition to measure time with a 12-hour standard has been effective since ancient times. Subsequently, AM and PM remain to be a common and yet ambiguous tradition of how people refer to time. This time convention is also might be confusing for the writing because it has multiple rules regarding how to write these abbreviations.Įven though the 12-hour clock is peculiar to many countries and cultures, other nations still face issues with the proper comprehension of AM and PM. It might be difficult for the people who use only a 24-hour clock to memorize when it is AM or PM. However, the 12-hour system has its flaws with the ambiguity in the understanding.
