La fórmula
Normalize both dates to local midnight, then days = round((target − from) / 86,400,000). Positive means upcoming; negative means past; zero means today. Weeks = floor(|days|/7); months ≈ |days|/30.4375.
Ejemplo resuelto
- From 2026-07-22 to 2026-12-25
- Civil-day gap = 156 days
- 156 = 22 weeks + 2 days · ≈ 5.1 months
Resultado: 156 days until Dec 25, 2026
How the countdown is counted
This is a one-sided date span: “how long until X?” rather than an unordered difference between two arbitrary dates.
Default “from” date
If From is empty, we use today in your browser’s local timezone. Both dates are treated as midnights — time of day is ignored.
Past dates
If the target is before the from date, we show “N days ago” with a past-date badge instead of a negative countdown.
Vs date difference
Date difference always returns a positive span between two dates. Days-until preserves direction (upcoming vs past) and highlights a single target.
