Do not abbreviate the year 2020 as "20" when writing the date. Use "January 3, 2020," not "1/3/20," when writing the date. While many of us are accustomed to abbreviating years—for example, writing 2019 as "19"—doing so in 2020 can be hazardous. Abbreviating years was common in the past, before a certain number of years were completely written out: "17th" or "18th" century. But even today some people may assume that you are referring to the decade rather than the year if you use an abbreviation. For example, they may think you are saying "1930's style" rather than "1930's." Avoid these pitfalls by writing the full year.
In English-speaking countries, dates are usually written as sentences using the present tense: "February 2nd is Valentine's Day"; "October 18th is Columbus Day". Although it is possible to write dates in the past tense ("February 2nd was Valentine's Day""), this usage is rare.
The year is a numeric value representing the actual count of days from January 1st to December 31st. It is therefore necessary to write the year in whole numbers only. In general practice, if there are less than 10 months in the year, then they will all be written out. So, for example, if February has six days instead of seven, then the year will be said to be "short".
Abbreviations are used because they're easier to say than whole numbers; however, that doesn't mean we should abuse this practice. It's best to avoid them when possible.
Years divisible by 100: Use the following format: MM/DD/YY. So, for January 1, 2021: 01/01/21. Years not divisible by 100: Use the following format: YYMMDD. So, for January 1, 2021: 210101.
The only exception is when referring to the year 2001, since it is a common abbreviation for Anno Domini (Latin for "in the year of our Lord").
So, to write 2021 in short form, simply use the word "twenty-one" followed by the month, day, and year.
Writing years in short form is useful when making plans or making notes by hand. Although computers make things easier these days, it's good to know the manual way to do things.
For the complete year of 2020, the dates must be written in their entirety, rather than simply the final two numbers of the "year." For example, if you wish to write January 13, 2020, use the whole date, 13/01/2020, rather than 13/01/2020. There are no years between 2000 and 2029, so there is no need to specify which year you are writing.
Years from 1000 to 1999 were designated as common years, so they had 365 days each. However, since 2000 has been a non-common year, it has 366 days.
The day of the month always has 2 digits, so for January 13, 2020, you would write 013 not 0130. If you wanted to write the whole date, you would write 20120313 instead of 20200113. Years from 1900 to 1999 that are not common years will have an extra day in February if they fall on a weekday.
February 29th is a legal holiday in both Canada and the United States. In Canada, it's called "Civic Holiday." In the U.S., it's called "New Year's Day."
January 1st is a federal holiday in Canada, but not in the United States. In Canada, it's called "Canada Day."
Authorities advise that abbreviating "2020" on papers may expose you to fraud. The new year has barely begun, giving scammers a fresh opportunity to falsify papers. Authorities advise that reducing "2020" to just "20" may expose you to fraud. Criminals may use your shortened paper to create more than one identity in order to commit crimes as well as escape detection.
The fundamental concept is to jot down a date, such as January 1st, 2020. If you shorten it to 1/1/20, someone may add two more numbers to the end to change the year. This method doesn't work for years before 1900 or after 2100 because there aren't sufficient digits left over to add two more numbers.
After you've done this, you can check whether the year is divisible by 100 without carrying the decimal point. If it is, then you just need to add another 9 to the end of the year to get back to where you started. For example, if you wrote down 1/1/2009, you would know that 2009 was a normal year because it was divided by 100. There are not enough digits left over to add another number to it and have it make sense. However, if you had written down 12/31/2008, you would know that 2008 was not a normal year because it wasn't divided by 100. There were too many digits left over when you did the calculation.
When referring to the year 2019, Americans typically use the phrase "twenty-nineteen." This is because American dates follow the ordinal system, which assigns a number value to each month of the year: January is 1 and December is 12. As such, "twenty-nine nineteen" would be interpreted as February 29th, March 19th, and so on.
In British English, "nineteen ninety-nine" would be understood as referring to 1999 rather than 2019. This is because the British date system does not have a month 0; instead there are 12 months in a year. Thus, "nineteen ninety-nine" would be interpreted as February 28th, March 18th, and so on.
In Australian English, "nineteen ninety-nine" would be interpreted as referring to 2019 because there are still only 30 days in an ordinary year. However, if "ordinary years" were replaced with "leap years," then "nineteen ninety-nine" would be interpreted as 2000 due to the addition of a 31st day in a leap year.
In 2020, the year will be "twenty-twenty," and in 2115, the year will be "twenty-one-fifteen." The number 2020 has several different meanings in common usage. It is the standard calendar year, it is also the chemical symbol for oxygen, and it is the atomic number of uranium.
The year 2037 is called "a thousand twenty" in English and French. In Spanish it's called "un mil veintiuno". Other languages that use numbers to denote years include Arabic (2039), Chinese (2051), Hebrew (2040), Indonesian (2041), Japanese (2045), Korean (2045).
Some words that end in "2020" may need an "s" after them when used as a year: the Year 2020, the decade 2020, the century 2020. Other words without an "s" can also be used as year names: Jackson, Lincoln, Washington, and Bemis.
Words that start with the letter "y" followed by any other letter are commonly used as year names. These include 2013, 2017, and 2019.
