Example 1: If it is 7 o`clock of the .m in a 12-hour clock and Susie wants to convert it to a 24-hour hour, what time should she set in the 24-hour clock? Solution: The hours and minutes remain the same from 1:00.m to 23:59.m. Therefore, 7 a.m. is represented as 7:00 a.m. in the 24-hour clock. The natural day-night division of a calendar day is the basic basis for which each day is divided into two cycles. Originally, there were two cycles: a cycle that could be followed by the position of the sun (day), followed by a cycle that could be followed by the moon and the stars (night). This eventually evolved into the two 12-hour periods used today, one called “a.m.” from midnight and the other called “p.m.” from noon. Noon itself is rarely abbreviated today; but if so, it is called “M”. [1] Abbreviations a.m.
and p.m. are usually written in lowercase if they are part of a continuous text. But this is not a rule as such. They can also be capitalized in the form of AM and PM. The only care to keep in mind is that when capitalizing letters, there is no period. For lowercase letters, the letters are followed by a period (10 a.m. or 10 p.m.). Small caps may be considered when used in continuous text to improve readability. This rule gets a little confusing when you take a look at 12pm or 12pm. For example, 12 o`clock in the morning – or ante meridiem – doesn`t make sense if you look at the rule because it doesn`t really come after midnight. When describing a vague time of day, a speaker may say the phrase “seven-thirty, eight” to mean at 7:30 or 8:00.m.
Such wording can be misinterpreted for a certain time of day (here 7:38), especially by a listener who does not expect an estimate. The phrase “about seven-thirty or eight” makes this clear. The 12-hour time convention is common in several English-speaking countries and former British colonies, as well as in other countries. This is an example of a duodecimal system. AM and PM are Latin words used to reference time. AM and PM are the abbreviated terms for Ante meridiem and Post meridiem, which means before noon or noon or afternoon or noon. The initial 12-hour period, which lasts from midnight to noon, is called AM, while the next 12-hour period, which lasts from noon to midnight, is called PM. AM and PM are both Latin terms used to represent time in the 12-hour convention. AM. means Ante Meridiem and P.M. means Post Meridiem.
Meridiem is a Latin word that essentially means noon (Meri means middle and Diem means day). Therefore, Ante Meridiem means “before noon” and Post Meridiem means “afternoon”. In the 12-hour system, AM and PM are used before noon and afternoon respectively. For many people, one of the most confusing things about time is understanding whether 12 p.m. is midnight AM or PM. Similarly, what is 12 called at noon? According to the convention, 12 p.m. means midnight and 12 p.m. means noon. However, to avoid confusion, it is best to use 12:00 and 12:00. “Noon” means “noon” or 12 o`clock of the day. “Midnight” means 12 o`clock (or 00:00) during the night.
You can also use the system 24 hours a day, where 12:00 is noon and 00:00 (or 24:00) is midnight. AM and PM are units used to represent the time in a 12-hour clock. From midnight to 11:59.m., the time is represented as AM, and from 12:00 p.m. at 11:59 a.m. she is represented as PM. AM stands for Ante Meridiem and PM stands for Post Meridiem. 4. I often tend to be confused between AM and PM, what should I do? When speaking, it is common to round the hour to the next five minutes and/or express the time as the past (or too much) of the next hour; For example, “Five Pasts” (5:05). Minutes after the hour means that these minutes are added to the time. “Ten to five” means 5:10 minutes to, from and from the hour means that these minutes are subtracted; “Ten out of five,” “ten to five,” and “ten to five” all mean 4:50. The daily cycle starts at 12:00 (usually specified at 12:00 .m), lasts until 12:00 (usually specified at 12:00 .m) and lasts until just before midnight at the end of the day.
The 12-hour clock was developed from the second millennium BC and reached its modern form in the 16th century AD 1. How to convert 12-hour time format to 24-hour time format? Time is divided into hours, minutes and seconds. Every day lasts 24 hours, every hour 60 minutes and every minute 60 seconds. For example, 8:20 means 8 hours and 20 minutes. The time is displayed in two ways. The first is through a 24-hour clock, and the other is through an AM PM clock. The abbreviation “AM” stands for ante meridiem (before the meridian line crossed the sun or time between midnight and 11:59 a.m.) PM stands for post-meridity (after the meridian line has crossed the sun or time between noon and 11:59 a.m.). You`re not the only one confusing AM and PM. To eliminate this confusion, Vedantu has provided this information to help you understand these complete forms with the utmost clarity. Read this information as often as you need it and try to apply it in daily practice. Apply them when you look at your watch or when someone asks you the time.
To help you with many of these other abbreviations, Vedantu has dedicated an entire website to fill out forms. Similarly, some American style guides recommend clarifying either “midnight” with other contextual cues, for example. B by specifying the two dates between which it falls, or by not referring to the term at all. For an example of the latter method, “midnight” is replaced by “11:59 p.m.” for the end of a day or “12:01 a.m.” for the beginning of a day. This has become common in the United States in legal treaties and for plane, bus or train schedules, although some schedules use different conventions. Sometimes, when trains run at regular intervals, the pattern can be broken at midnight by postponing the midnight departure by one or more minutes, para. B example at 23:59 .m or 12:01.m. [29] How to convert the time on a 24-hour clock to the 12-hour system: To understand this timing system, you can simply think of it as two different time zones of 12 hours each, which represent day and night. Basically, 24 hours are divided into two time zones (before noon and afternoon), each lasting 12 hours.
The first duration of 12 hours starts at midnight and lasts until noon, which is called by AM (12:00 to 12:00). The second duration of 12 hours starts at noon and lasts until midnight, marked by PM (12:00 to 12:00). Minutes can be expressed as an exact number of minutes after the time indicating the time of day (e.B. 6:32 p.m. is “six thirty-two”). In addition, if you express time with the formula “past (after)” or “to (before)”, it is common to choose the number of minutes below 30 (e.B. 6:32 pp.m. is conventionally “twenty-eight minutes to seven” and not “thirty-two minutes after six”).
Anyway, as far as I know, the 12-hour clock goes back a long way to ancient Mesopotamia and Egypt. The Egyptians used a 12-hour sundial to indicate the time of day and a 12-hour water clock at night. The Romans also used a 12-hour clock. Most other languages do not have formal abbreviations for “before noon” and “afternoon,” and their users use the 12-hour clock only orally and informally. [Citation needed] However, in many languages, such as Russian and Hebrew, informal terms such as “9 a.m.” or “3 a.m.” are used. Why do we use a.m.-p.m. Time reading system? The 24-hour day (i.e. 1300 for 1 S.m.) that the army uses seems so much easier.
For this reason, the time is marked with the suffix AM or PM. so that we can identify which part of the day the time reference belongs to, but you probably already knew this part. Also, in situations where the relevant time is obvious or has been mentioned recently, a speaker may omit the time and simply say “quarter to (hour)”, “half more” or “ten until” to avoid a thorough sentence in informal conversations. These forms are often used in television and radio programs that span multiple time zones within an hour of each other. [17] Time is an entity that has aroused people`s curiosity since time immemorial. .
