How is the day count calculated?

The tool compares your target date to today's date at midnight local time, so the count is always in whole calendar days — it's not affected by what time of day it currently is.

What happens if I pick a date in the past?

The tool automatically switches to "days since" and shows how long ago that date was, along with the weeks and approximate months elapsed.

How is 'months' calculated?

It's an approximate calendar-month difference between today and the target date, accounting for whether the target day-of-month has passed yet in the current month — useful as a rough sense of scale alongside the exact day count.

Is my date sent anywhere?

No. Everything is calculated locally in your browser using JavaScript's Date object — nothing is transmitted or stored.
