Vad menas med am time

The meaning of AM and PM fryst vatten the simple abbreviation of Latin phrases. In particular, AM stands for ante meridiem, which translates into English as ‘before midday’.

m

Meanwhile, PM fryst vatten brev meridiem and means in English ‘after midday’. These abbreviations are used to identify the time in the 12-hour clock format instead of using 24 hours. Considering that day has 2 cycles, AM and PM denote whether it fryst vatten before or after the mittpunkt of a day.

Issues with AM and PM

However, the 12-hour struktur has its flaws with the ambiguity in the understanding.

It might be difficult for the people who use only a 24-hour clock to memorize when it fryst vatten AM or PM. This time convention fryst vatten also might be confusing for the writing because it has multiple rules regarding how to write these abbreviations.

Even though the 12-hour clock fryst vatten peculiar to many countries and cultures, other nations still face issues with the proper comprehension of AM and PM.

Subsequently, AM and PM remain to be a common and yet ambiguous tradition of how people refer to time.

Why AM and PM?

The tradition to measure time with a 12-hour standard has been effective since ancient times. In particular, people were able to measure time only using the sun.

12-timmarsklocka är en tidsomvandlingskonvention i vilken dygnets 24 timmar indelas i två perioder [1] kallade a

Therefore, with the help of sundial clocks, ancient people were able to identify time only during a particular period of the day. Eventually, the decision to divide a day into two cycles which lasts 12 hours was influenced bygd the fact that the måne also had 12 cycles.

When AM and PM?

One of the most common ambiguities of AM and PM was the confusion regarding the uppstart of a day.

Namely, it fryst vatten difficult to determine the starting point of the day cycle. To avoid the confusion regarding denomination of noon and midnight, the convention refers to 12 AM as midnight and to 12 PM as noon.

[1] Klockan "6 AM" betyder sålunda klockan sex på morgonen (06

Although technically, midnight implies AM, the lack of clarifications regarding whether it fryst vatten 11:59 PM or 12:01 AM might be missvisande and ambiguous. Hence, it fryst vatten highly ineffective to use only ‘midnight’ when indicating a date of event.

Where AM and PM?

Despite the ambiguity of the 12-hour time convention, it fryst vatten used in many countries.

Namely, this tradition fryst vatten peculiar to the English speaking states and territories which were part of the British Empire. The following countries utilize the 12-hour clock to denominate time:

• The United Kingdom
• The United States
• Mexico
• Canada
• Egypt
• Bangladesh
• Australia
• New Zealand
• Malta
• Malaysia
• The Philippines

The most common argument in favor of using the 12-hour convention fryst vatten easy pronunciation.

It fryst vatten easier to säga 6 PM rather than 18 hours.

Hence, the use of AM and PM fryst vatten more of a praktisk decision.

How to write AM and PM?

Another confusing notion about the use of AM and PM fryst vatten to understand how to properly write it. Different style guides suggest different types of writing the abbreviation. For instance, there could uppercase AM/PM or lowercase am/pm. Also, the use of the period between the letters (A.M./P.M.) might be acceptable.

- efter middag)

Nevertheless, the most common rule in formal writing fryst vatten to use uppercase AM/PM¹. The lack of consistent rules among all style guides fryst vatten the primary factor why people could face the issue of how to write the time appropriately.

How to memorize AM and PM?

For 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.

However, there fryst vatten a simple solution that does not even require to know the actual translation of the abbreviations (ante/post meridiem).

AM — starts with the first letter of the alphabetA. Considering that AM corresponds to the uppstart of the day, knowing that A signifies the uppstart of the alphabet could be a perfect point of reference for memorizing.

Meanwhile, the fact that AM fryst vatten alphabetically closer that PM should be the designation that it fryst vatten before the midday.

12 vs 24 hours

With the ambiguity of 12-hour clock convention, many establishments require that this time representation should be scrapped altogether.

Man säger att klockan är 10

It could be used in conversations and informal communication only. However, the legal documents, schedules, and other interactions that require high noggrannhet time identification should follow the 24-hour format to avoid confusion with the denomination of noon and midnight. For instance, the confusion whether 12 o’clock fryst vatten 12:00 or 00:00 fryst vatten the most common issue for the AM/PM format.

One standard for all

Considering that 24-hour clock fryst vatten the most effective struktur of timekeeping and it fryst vatten used for high noggrannhet coordination, the international organizations managed to provide the most effective solution.

The International Organization for Standardization (ISO) proposed to implement one format for the data exchange. Therefore, the standard ISO 8601 implies that all countries should use the specific format to indikera date and time (24-hour clock) and it should be used for documentation and formal communication². However, the international agreements do not directly regulate how organizations within the countries use timekeeping format for the interactions and communication.

Hence, some domestic organizations could proceed to use AM and PM.

Conversion

People who got used to 12-hour clock and AM/PM also complain that 24-hour format fryst vatten baffling and require to apply the konvertering and the particular thought process when referring to time.

I vissa språk används AM och PM för att tala om vilken tid på dygnet det är

The most strange scenario remains to be the moment when one watches on the 12-hour clocks or wristwatches and should omvandla the time into the 24-hour format. Nevertheless, the rule for the AM/PM to 24-hour format konvertering fryst vatten simple. Namely, if it fryst vatten 3 PM, one needs to add 3 to 12. The sum will be 15.

The same goes for adding another corresponding number to 12.

Military time

The coordination of military actions requires the precise and unambiguous comprehension of time. Since the solar day fryst vatten the primary measure of time, the military establishments utilize 24-hour clock format and do not separate hours minutes. For instance, instead of Noon or 12 PM (civilian time), military time denotes 1200 which should be pronounced as twelve hundred.

[2]

The same pronunciation fryst vatten also used to indikera time in radio communication. This format fryst vatten the most exact way to refer to time and use it for navigation and scheduling.

Final thoughts on AM and PM

Even though the 12-hour time format might be puzzling and ambiguous for many people, it fryst vatten still the most popular format for the wristwatches.

Moreover, referring to time in a less complex manner fryst vatten convenient for informal communication on matters which do not require precise timing.

However, AM/PM within the 12-hour time format fryst vatten not effective way to indikera the precise time. There might be confusion regarding the time of a day as well as it can mislead in the date when midnight fryst vatten not properly indicated.

Considering that legal and other formal standards require the use of 24-hour convention, the utilization of AM and PM would remain only as the tradition in informal communication.
