Writing date 17 December in English can be done in a variety of ways. Here are some common ways to write the date 17 December in American English.
When you prefer to write the date in American English, usually the month comes before the day, then followed by the year. For example: The 17th day of the month December, in the year 2019, then the date in American English should be written as:
December 17, 2019
Tuesday, December 17, 2019
Dates written as December the 17th or December 17th are not incorrect, but are less common in American English.
How to write the date 17 December in numbers?
In American English, if you want to write the date in all-numeric, you will need to use the following style. Here, too, the month comes first, then the day, then the year.
12/17/19 or 12.17.19 or 12-17-19
12/17/2019 or 12.17.2019 or 12-17-2019
Dec. 17, 2019
The International Standard date formats
In an effort to avoid miscommunication between people using the British date format and those using the American date format, an International Standard was developed. If an Australian writes December 17, 2019 as 17/12/2019, but an American writes the same date as 12/17/2019, who’s right? The international standard recommends writing the date as year, then month, then the day: YYYY-MM-DD. So if both the Australian and American used this, they would both write the date as 2019-1217-.
Writing the date this way avoids confusion by placing the year first. Much of Asia uses this form when writing the date. For example:
December 17, 2019 would be written as 2019 December 17. (Did you notice there’s no comma?).
