Hi, Tony,
Should I use "the" in the below sentence and whether I should use cardinal number for the date 23 January 2022, so it becomes 23rd January 2022.
"23" is a cardinal number, and "23rd" is an ordinal number.
The property was settled on the 23 January 2022.
You don't use the article for dates in writing. In AmE, you should say:
- The property was settled on January 23, 2022.
In BrE, you should say:
- The property was settled on 23 January, 2022.
It is mostly in speech that the article can appear: The property was settled on January the 23rd / on the 23rd of January.
It would perhaps be more accurate to say: The purchase of the property was settled on ...
