javascript regex iso datetime

Question

does anyone have a good regex pattern for matching iso datetimes?

ie: 2010-06-15T00:00:00

Answer 1

For matching just ISO date, like 2017-09-22, you can use this regexp:

^\d{4}-([0]\d|1[0-2])-([0-2]\d|3[01])$

It will match any numeric year, any month specified by two digits in range 00-12 and any date specified by two digits in range 00-31
