Use Countdown Timer to calculate dates, deadlines, differences and time conversions.
Time has quirks: months and years vary in days, timezones change with daylight saving and calendars have rules.

- Enter dates, times and parameters.
- If timezone exists, select city/region correctly.
- Use Quick mode for direct result and Full mode for context and notes.
- Copy the result to your agenda, contracts or planning.
Perguntas frequentes
Why aren't months/years just 'days/30'?
Because real calendars vary.
Can daylight saving change my result?
Yes.
Can I calculate for past/future dates?
Yes, using a reference date or selecting dates directly.
Technical notes
Fórmula usada: Δs = ⌊(Alvo − Agora)/1000⌋; dias=⌊Δs/86400⌋; horas=⌊(Δs%86400)/3600⌋; min=⌊(Δs%3600)/60⌋; seg=Δs%60.
Unidade e escopo: calculamos a diferença entre a data/hora alvo e o “agora” e quebramos em dias, horas, minutos e segundos.
