About Us
Learn more about our mission, our values, and the team building high-performance calculation utilities.
Our Mission
We believe that basic, utility calculation tools should be universally accessible, precise, secure, and completely free. We built Datumsrechner to save professionals, lawyers, project managers, and individuals the time and anxiety involved in calculating critical notice periods and contract dates.
Accuracy First
Date calculations can have major legal and financial impacts (like missing a contract termination deadline). That is why our engine is regularly audited and accounts for leap years, weekends, and complex state-specific regional holidays automatically.
Privacy & GDPR
We do not track you, nor do we require you to sign up. All calendar calculations occur locally right inside your browser. Your dates, values, and calculations never leave your computer, keeping your information 100% private.
Always Free
Datumsrechner is and will always remain 100% free of charge. No premiums, no memberships, no paywalled features. Supported entirely by non-obtrusive static ads to pay for hosting and development costs.
