How to use this calculator
- Enter the target date.
- Read how many days remain until it (today's date is read automatically from your device).
Assumptions
- Uses your device's current date — if your device's clock or timezone is wrong, the result will be too.
- A target date in the past shows a negative number of days.
Technical details: what the fields mean
- Target date
targetDate - The date you're counting down to.
Methodology
Days remaining = target date − today's date (read from your device), in whole days.
Worked example
