The date format is usually written as mm/dd/yy and sometimes the month written out followed by the day followed by a comma and the year. My question is: is it academically acceptable to write the date in mm.dd.yy format? I like the . . . format better than the / / / format, which is why I ask the question.
The International Standard ISO 8601 is YYYY-MM-DD. See Wikipedia and A summary of the international standard date and time notation.
Sadly this is not used by everyone as can be seen in this article about date formats per country:
- The most popular order is day-month-year (Little-Endian, cyan in the image), used by about 57% of the world population.
- Next is year-month-day (Big-Endian, yellow), used by about 29%.
- Then month-day-year (Middle-Endian, magenta), used by about 6%.
- The remaining 8% use a mix of the above.
But, in the end the most important is the standards used in your university or the conference or journal you are sending your papers to.
If someone else has authority over your format, for example your advisor or the publisher of the journal you're writing for, then follow that someone's format requirements. If there's nobody with such authority, or if the person with authority doesn't care about the format, then use whatever format you like (but make sure you use it consistently).
