How can I change this date format to seconds?
<div class="calendar" data-fixeddate="July 16, 2017 00:05 am">...</div>
Can we convert using JavaScript or JQuery?
Try this in your browser console:
new Date('July 16, 2017 00:05 am').getTime() / 1000
Date.getTime returns the date in milliseconds, divide by 1000 to get seconds.
