Calculadora de diferencia de fechas
Calcula el número exacto de días, semanas, meses y años entre dos fechas.
Total days
30
| Weeks | 4 and 2 days |
| Months | 1 and 0 days |
| Years | 0 and 30 days |
Cómo usar
- Pick a start date and an end date, in either order.
- The total days and the week, month and year breakdowns appear immediately.
- Turn on Include both endpoints to count both the first and the last day (+1).
Notas
All math is done on UTC calendar days, so time zones and daylight saving never change the result. Month arithmetic follows the calendar and clamps to the last day of the target month (for example, one month after Jan 31 is Feb 28).
Preguntas frecuentes
- Why do identical dates give 0 days?
- The tool measures the gap between the two dates. If you want to count both days themselves, turn on Include both endpoints and the same pair gives 1 day.
