About this app

DaySpan is your precise, privacy-focused date calculator, designed for office professionals, students, freelancers, and project managers. Effortlessly calculate the time span between two dates and predict future (or past) target dates with ease.

Built with a commitment to privacy, DaySpan performs all calculations locally on your device. No data is collected, and no internet connection is required.

DaySpan simplifies date math into clear calendar days, working days, and weekend days.

📅 Date Span Calculation:
Instantly find the exact number of days between any two calendar dates.

📊 Workday Breakdown:
Get a clear breakdown of actual working days (Monday to Friday) and total weekend days within your period.

🎯 Target Date Prediction:
Add or subtract days (forward or backward) from a start date to predict the exact target date, including the day of the week.

✅ Flexible Counting Options:
Choose whether to include the start date, the end date, or both in your calculations.

🔒 Your Privacy, Your Data:NO personal data is collected, stored, or transmitted. All calculation history saved in the app uses your device's local storage and can be cleared by you at any time.

DaySpan follows a standard Monday-to-Friday workweek rule and does not automatically adjust for regional public holidays. For formal payroll, contract, or attendance matters, please rely on official calendar rules. A local history of your most recent calculations is available for easy reference and can be cleared by you.
