How To Validate 12-hour Time With Regex (regular Expression)

I want to validate a 12-Hours time format like (01:05 PM) in PHP, Javascript and HTML. I tried this: ((([1-9])|(1[0-2])):([0-5])(0|5)\s(A|P)M) But I don't know why it doesn't work

Solution 1:

Try ,

^(1[0-2]|0?[1-9]):[0-5][0-9] (AM|PM)$ 

You may test here

Solution 2:

try this :

(((0[1-9])|(1[0-2])):([0-5])([0-9])\s(A|P)M)

test regex here

try this for case sensitive AM|PM|am|pm : `

(((0[1-9])|(1[0-2])):([0-5])(0|5)\s(A|P|a|p)(M|m))

`

Solution 3:

This will work for both pm/am and PM/AM and prefixed with or without 0(Zero)

/^(0?[1-9]|1[012])(:[0-5]\d) [APap][mM]$/
