How to convert Date to Unix Timestamp in Javascript

In Javascript, Date object has getTime() method and it returns number of milliseconds since the Unix epoch which is January 1, 1970 00:00:00 UTC

And unix timestamp are mostly represented in seconds not milliseconds and so we'll be converting milliseconds to seconds by dividing it by 1000.

    const date = new Date(); // Or any Date('YYYY-MM-DD')
    const unixTimestamp = Math.floor(date.getTime() / 1000);

Happy converting date!
