How it's calculated
The gap between the two moments in milliseconds is broken into whole days, then whole hours from the remainder, then whole minutes from what's left — plus the same total expressed fully in hours and in minutes for convenience.
Frequently asked
Does this handle time zones?
No — both fields use your browser's local time zone. If comparing moments across zones, convert them to the same zone first (the Time Zone Converter can help), or note the offset yourself.
