In this article, we’ll look at how to check if date is less than 1 hour ago with JavaScript.
How to check if date is less than 1 hour ago with JavaScript?
To check if date is less than 1 hour ago with JavaScript, we can compare the timestamp difference to the value for one hour in milliseconds.
For instance, we write
const lessThanOneHourAgo = (date) => {
const HOUR = 1000 * 60 * 60;
const anHourAgo = Date.now() - HOUR;
return date > anHourAgo;
};
to define HOUR to be the value of one hour in milliseconds.
Then we use Date.now() - HOUR to get the timestamp in milliseconds for one hour ago.
Finally, we compare the timestamp of date to anHourAgo with
date > anHourAgo
Conclusion
To check if date is less than 1 hour ago with JavaScript, we can compare the timestamp difference to the value for one hour in milliseconds.
