Constraint for working hours

[nour_alhajali]

Hi,
I am looking for the input to look like 8:00 a.m - 5:00 p.m
I tried to have in the constraint ```
regex(., '^[1]|1[0-2]:[0-5][0-9] [ap].m. - [1-9]|1[0-2]:[0-5][0-9] [ap].m.

``` but it did not work. Kindly advise on the correct constraint to standardize the respondents' inputs on the working hours.
thanks

if-statement, note and relevant to make it a constraint.

Thanks a million for the explanation. I am looking for one question about the start and end working hours. In the above way, it will take two questions. If it is possible to kindly share the correct constraint syntax for the regex that will be greatly helpful.

@nour_alhajali, Do you intend to use 12 Hour format e.g am - pm? Can you use 24 Hour format?

[nour_alhajali]

sure, we can use any of them 12 or 24
but at the end the respondent can answer business hour question at once
