DateSpanLedger

Make everyday date planning easier with a focused, offline toolkit. Date interval Compare two calendar dates with clear total-day results and a calendar breakdown in years, months, and days. Choose whether the boundary days count, and see whether the interval runs forward or in reverse. Workday calculator Define your own weekly rest days and enter up to 100 excluded dates. The result counts only the rules you configure and clearly does not claim knowledge of local public holidays. Personal dates Keep anniversaries, plans, and other meaningful dates in one private local list. Add a title, date, optional yearly repetition, and notes. Review upcoming entries or remove entries you no longer need. Recent calculations Your latest interval and workday results are saved locally for quick reference. Clear the history whenever you choose. Helpful by design Every date field uses the unambiguous YYYY-MM-DD format. Guidance explains boundary counting, month-end handling, and custom workday rules. No account, network connection, system calendar access, advertising, or payment is required.
