Cos'è un contatore giornaliero?

A day counter calculates the number of days between two dates, days since a past date, days until a future date, or a countdown to an event. It accounts for leap years, varying month lengths, and year boundaries.

Total days = End Date − Start Date  |  Business days = weekdays only (Mon–Fri)

Use it for project timelines, countdowns, age or tenure in days, and event planning.

Date Format

Use YYYY-MM-DD (e.g. 2025-02-15). Dates from year 1 to 9999 are supported.
