Write dates as you usually do, 31.12.2026 or Dec 31, 2026, and calculate in words: deadline - start, start + 10 workdays, days until 31.12.2026. Month lengths and leap years are handled for you.
deadline - start: the number of days between two dates.01.10.2026 + 30 days: the date 30 days later, with its weekday.start + 10 workdays: a deadline in working days, Monday to Friday.days until 31.12.2027 and workdays until 31.12.2027: counted from today.weekday 31.12.2026, age 05.03.1988, today + 14 days.The difference between two dates is the number of nights between them: from October 1 to October 2 is one day. Months are added by the calendar: 31.01.2027 + 1 month gives Feb 28, 2027, because February has no 31st, and the calculator says so. Public holidays are not counted, only Saturdays and Sundays.

No, only weekends are: Saturday and Sunday. Holidays differ by country, so subtract them by hand if needed.
31.12.2026, 2026-12-31, Dec 31, 2026 or 31 December 2026. A date written with slashes, such as 13/10/2026, is read as a division so it is not confused with a calculation.
Write today + 45 days or days until 31.12.2027. “Today” comes from your device's clock.
