How to convert human-readable date to epoch time?

human_readable_date = '2022-09-13 00:00:00'
epoch = int(datetime.datetime.strptime(human_readable_date, '%Y-%m-%d %H:%M:%S').timestamp())
print(epoch)

// Convert human readable date to epoch
const humanReadableDate = '2022-09-13 00:00:00';
const epoch = Math.floor(new Date(humanReadableDate).getTime() / 1000);
console.log(epoch);
