FAQ
How does days-until differ from a date difference?
It is directional: it tells you how many days remain until a target, or how many days ago it was if the date has passed.
What if I leave the From date blank?
Leaving From blank counts from today; the To date is the target you want to reach.
What does it show on the target day?
If the target is today, the result simply says the date is today.
Does the Days Until Calculator send my data to a server?
No. The Days Until Calculator runs entirely in your browser — your inputs never leave your device, and nothing is uploaded or stored.
