Choose whether to include the end date. • Add / Subtract — shift any date by years, months, weeks and days, and see the resulting date and its day of the week. • Age — exact age in years, months and days from a birth date, total days lived, the day you were born, and a countdown to your next birthday. • Working days — count business days (Mon–Fri) between two dates, and optionally exclude your own custom holiday dates. • Week number — ISO week number, day of the year, days left in the year and the quarter for any date. SAVE YOUR RESULTS (the “List” difference) • Save any calculation with a label like “Days until exam”, “Baby’s age” or “Contract end”. • Ages and countdowns recompute to today automatically each time you open the app. • Edit, delete and reorder your saved results. Save as many as you like.
