How can I convert a string to a Datetime object?

Question

I am dealing with an old database. I need to compare dates to each other. One date type is datetime and the other is a string.

When I try to convert

07/25/2019 06:30AM

using new Date(Date.parse(07/25/2019 06:30AM))

I get the error Invalid Date.

new Date('07/25/2019 06:30 AM')

but your date format is invalid because it requires space between time (06:30) and AM

Try

new Date(Date.parse("07/25/2019 06:30"))

You don't need the AM that is redundant to the fact of the time itself of 06. I can see using that if you were to use 6:30 but not 06:30.

You can make it by two ways:

Remove AM:

    let dt = new Date('07/25/2019 06:30');
    alert(dt);

Add space between hour and AM:

    let dt = new Date('07/25/2019 06:30 AM');
    alert(dt);

Try to use the following approach to to avoid some strange bugs while parse Date:

let date_string = "07/25/2019 06:30 AM"
let [M,d,y,h,m,s] = date_string.split(/[/ :]/);
h = (s == 'AM') ? h : (parseInt(h) + 12);    
let yourDate =  new Date(y, parseInt(M)-1, d, h, parseInt(m));
console.log(`yourDate ${yourDate}`);
