Question

Can someone tell me how to check how often WordPress checks for updates?

Does the check for update depend on user interactions? for instance if my website has zero traffic and zero user interaction, is WordPress still able to check for updates?

Answer 1

There is also a dedicated page for updates which can be reached from
the dashboard menu. It’s helpful when you want to do bulk updates of
multiple plugins instead of updating each one separately. It also has
a “Check Again” button which checks for new updates. By default,
WordPress does this check every 12 hours.

The 12 hour waiting period is defined in WordPress core on Line 147 of
the wp-includes/update.php file, it’s the $timeout variable.
