Writing date 31 January in English can be done in a variety of ways. Here are some common ways to write the date 31 January 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 31st day of the month January, in the year 2019, then the date in American English should be written as:
January 31, 2019
Thursday, January 31, 2019
Dates written as January the 31st or January 31st are not incorrect, but are less common in American English.
How to write the date 31 January 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.
01/31/19 or 01.31.19 or 01-31-19
01/31/2019 or 01.31.2019 or 01-31-2019
Jan. 31, 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 January 31, 2019 as 31/01/2019, but an American writes the same date as 01/31/2019, 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 2019-0131-.
Writing the date this way avoids confusion by placing the year first. Much of Asia uses this form when writing the date. For example:
January 31, 2019 would be written as 2019 January 31. (Did you notice there’s no comma?).
