Date Calculator

ClaudeCommunityby Online Alarm Kur

Date Calculator gives Claude exact date arithmetic instead of estimates. It counts the days between two dates, adds or subtracts days, weeks, months or years, and calculates business-day deadlines that skip weekends and official public holidays for a chosen country or region. It can also list a country's public holidays for any year and show which countries and regions are supported. It uses the same calculator as onlinealarmkur.com. Every result includes the rules that were applied and a link that opens the same calculation on the website, so users can check it themselves. All four tools are read-only and the server needs no account or authentication. Limitations: it works with Gregorian calendar dates only, not times of day or time zones. Holiday data covers official public holidays and does not mark half-day holidays, so critical legal or tax deadlines should still be confirmed with the relevant authority.
