Do you need a comma to separate the day from the month, and the date from the year?

When you write a date, you should use a comma to separate the day from the month, and the date from the year, e.g. He was born on October 8, 1977 or Today is Tuesday, August 8, 2019.

Correct: I was born on Saturday, October 8, 1977. Incorrect: I was born on Saturday October 8, 1977. Incorrect: I was born on Saturday October 8 1977. Incorrect: I was born on Saturday, October 8 1977.

If you put the day of the month first, e.g. 12 May 2012, then there is no need to include commas in the date.
