Thanks ww for your suggestions.

Your idea of turning the dates into timestamps was key, since this will allow me to compare the values much more easily than if they were formatted in calendar/time form.

Also, I was thinking that if there is a way that I can format the time and hour values from the original data so that they follow the dd/mm/yyyy hh/mm/ss format explicitly, this could also make things a bit easier from my end because it would allow me to easily check that all the values between the "/" are 2 digits long (except for the yyyy, of course). Anyways, just something that I'm thinking on :)

Thank you again for your incredibly valuable guidance on this!!
