## What is Date & Time Calculator?

Whether you're planning a vacation, scheduling a project or simply settling a "how many days until..." question, Date & Time Calculator gives you fast, accurate answers every time. This minimalist date duration calculator finds the exact number of days between two dates, and adds or subtracts time from any date with a single tap.

No more counting squares on a calendar or guessing the math in your head. From everyday planning to precise business scheduling, it's the date and time tool that quietly handles the numbers so you don't have to.

WHAT YOU CAN DO

• Add or subtract time — add or remove years, months, weeks, days, hours and minutes from any date to land on a new one.
• Business days between dates — count only the working days within a range, ideal for project timelines and leave planning.
• Add or subtract workdays — shift a date by a set number of working days, with customizable settings for your week.

*2024-10-18*

Es sollte optional eine 5,6 oder 7 Tage Woche eingebracht werden. Es ist doch ein unterschied ob ich für das gleiche Anfangdatum und Enddatum mehr Tage habe wenn ich nur 5 Tage Woche arbeite und nicht 7 Tage Woche. Das sind bei 2 Tagen mehr die Woche 274 Tage das Jahr

### 3/5 — Удалю

Не укладывается в голове, как можно утверждать такой дизайн пользовательского интерфейса, когда результат вычислений отображается вот так мелко, едва заметно.
