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 British English.

In British English, which is mainly used in Australia, the day is followed by the month, which is then followed by the year. The 31st day of the month January, in the year 2019, might be written in full (in order of complexity):


31 Jan

31 January 2019

31st January 2019

the 31st of January 2019

the 31st of January, 2019


The last two date formats are more formal. The “the” and “of” are optional but if you do use them, you must add both “the” and “of.” It is incorrect to say only “31st of January” or “the 31st January.”


As for the year, commas are not necessary when you write the date in British English, but you can if you prefer this style.

If you wish to add the name of the day, it should come before the date, and should either be separated by a comma or joined by “the” and “of.”


Thursday, 31 January 2019

Thursday the 31st of January, 2019



How to write the date 31 January in numbers?

If you prefer to abbreviate the date, you can use the following style in British English. Again, the day comes first, then the month, then the year.


31/1/19   or  31.1.19  or  31-1-19

31Jan2019   or  31-Jan-19

The most commonly used separator in the all-numeric date format is a forward slash (/). However, you can also use a hyphen (-) or a period (.).
