Sobre Esta Calculadora
Counting days between two dates sounds straightforward but quickly gets complicated when you factor in months of different lengths, leap years, and the difference between calendar days and working days. This calculator handles all of that automatically.
Switch to business-days mode and it strips out weekends, giving you the number of actual working days — useful for calculating payment terms, shipping lead times, legal notice periods, and project durations. The result is also broken down into years, months, weeks, and days so you can express the interval in whichever unit makes most sense.
All calculations run locally in your browser with no data sent to any server.
A Calculadora de Diferença de Datas encontra o número exato de dias, semanas, meses e anos entre quaisquer duas datas.
