Dates and numbers

How to show numbers, including measurements and money, and dates, including days of the week.


Numerals are easier to read than words when writing numbers for digital content, but consistency is key.

Dates and days

Days and months should be written in full. You can choose the best way to refer to an historical era.


Express units of measurements in miles or metres, not kilometres or yards.


Use the £ symbol, or p as an abbreviation of pence. Write out other currencies in full where possible.


Format a time with no space and no full stop, and write out fractions of hours in full.
