英语3月20怎么说

In English, March 20th is written and spoken as "March 20th" or "March the 20th." It is not necessary to include the word "the" before the ordinal number (20th), but it is a common practice. Here are a few examples of how you might say or write March 20th in English:

March 20th is my birthday.
I have a meeting on March 20th at 2:00 PM.
The deadline for the project is March 20th.

You can also abbreviate the month and the ordinal number, like this:

Mar. 20th
Mar. 20

Note that in English, the ordinal number is written with the letters "th" after it (20th, 21st, 22nd, etc.), except for the first, second, and third (1st, 2nd, 3rd).
