Dates
IDP lists these as ways to write a date: number or word form, and abbreviated days or months are allowed (IDP). The numeric forms can be read as day/month or month/day, so writing the month as a word removes any doubt.
| Format | Example from IDP |
|---|---|
| Month and ordinal | March 5th |
| Abbreviated month | Mar 5th |
| Ordinal first | 5th of Mar |
| Numeric | 03/05 or 5/3 |
Ordinal endings
IDP's rule: numbers ending in 1 take st (1st, 21st, 31st) except 11th; numbers ending in 2 take nd (2nd, 22nd) except 12th; numbers ending in 3 take rd except 13th; all others take th (IDP). A wrong ending is a wrong answer.

Times
You can separate hours and minutes with a colon or a full stop, so seven o'clock can be 7:00 or 7.00 (IDP). If the recording says the time is in the morning and the question does not, include it: IDP accepts 9.30 a.m., 9:30am, 9.30 A.M. or 9:30AM. If the gap is already followed by p.m., do not write it again; IDP's example answer is 5:00 or 5.00.
Know what quarter past, quarter to and half past mean: 6:15, 6:45 and 6:30 (IDP).
Phone and card numbers
In number sequences, speakers may say "O" for zero and "double" or "triple" for repeated digits, so "double seven" is 77 and "triple three" is 333 (IDP). Write the digits, not the words.
Frequently asked questions
Can I write 5/3 for 5 March in IELTS Listening?+
IDP lists numeric dates as acceptable, but writing the month as a word avoids day and month confusion.

Both. IDP says a colon or a full stop is fine.
What does 'double nine' mean in a phone number?+
