Everytime I get an upvote on this answer, I'm reminded that my answer doesn't actually answer the question.

OP: If you can parse your string into the following format, you can use one of the other answers. MM/DD/YYYY HH:MM:SS AM EDT (It's important to specify the timezone; epoch is based on the meridian)

let milliseconds = new Date("1/20/1982 5:00 PM EST").getTime()
console.log(milliseconds);
