The international format yyyy-mm-dd or yyyymmdd is also accepted, though this format is not commonly used. The formats d. month name yyyy and in handwriting d/m-yy or d/m yyyy are also acceptable.)
How dates are written around the world?
Youd think something as common and important as writing dates would be standardized by now. And in fact it is, ISO 8601 sets the international standard for writing dates as YYYY-MM-DD. The most common is the exact opposite of ISO 8601 and goes Day-Month-Year.
If you still want to put the date on your cover letter, make sure you format it properly. The correct way to format the date on your cover letter is [Month] [Day], [Year]. For instance, July 29, 2021.
