Javascript get Date() object from string time and date

Question

I am programming a facebook chat bot and I receive the date and time from the user, I want to create an object of type Date().

Accepted formats from user:

Date:

Time:

15:30 et
15:30
3pm et
3pm

Would you recommend me some library (I've looked at moment.js)? How would you parse these formats?

EDIT

For Time validation I use this regex:

/((0?[0-9]{1,2} ?(pm|am) ?(et|at)?)|(0?[0-9]{1,2}:0?[0-9]{1,2} ?(pm) ?(et|at)?)|(0?[0-9]{1,2}:0?[0-9]{1,2} ?(et|at)?))/

For Date validation I use this regex:

/(0?[1-9]|[12][0-9]|3[01])[\/\-\.](0?[1-9]|1[012])[\/\-\.]\d{4}/

Use new Date(15/9/2017) in case of dot (.) replace dot with ( '/' or '-') — Nitin Dhomse

Are those all the accepted formats? Would 2016-12-25 be rejected? — trincot

for now yes... I am slovak guy and I am programming for american people, what time do they use in America? I will paste the regex which is used for validation. — durisvk

Well, the date notation in the US usually has the month come first MM/DD/YYYY. Different from Europe. — trincot

JavaScript has quite limited date/time support, and it is generally recommended to use a library for any parsing requirements.

In my opinion, the defacto DateTime library for JavaScript it Moment.js.

Using Moment.js, you can supply a date string like in your example, along with a format string which describes the format your date string is in.

For example:

var date = moment("15.9.2017", "D.M.YYYY");

For times you can use the H:m:s format string, and there is also a timezone extension for extra timezone manipulation.
