About this game

Plan dates with clear calculations and personal date tracking that stays on your device.

Date interval
Compare two dates with a total day count, weeks and remaining days, and a calendar breakdown in years, months and days. Choose whether the start and end dates are included, and see the counting method explained. Reversed dates are handled with a clear direction note.

Date shift
Add or subtract days, weeks, months or years from a starting date. If the target month does not contain the original day, the result uses that month's final day and explains the adjustment.

Workday calculation
Choose weekly rest days and maintain up to 100 custom excluded dates or extra workdays. Counts use only the rules you configure; no regional holiday calendar is assumed.

Personal dates
Save anniversaries, plans and milestones with a title, date, optional monthly or yearly repetition, count direction, tag and note. Review upcoming dates, search or filter by tag, hide items, and archive or restore them.

Recent calculations and preferences
Reopen recent calculations with their inputs, copy results, remove individual history items or clear history. Choose a date display format, week start, default interval boundary, theme and text size.

Everything works offline. Date calculations and saved information remain in local app storage. The app does not read your system calendar or contacts and does not provide regional public holiday data.
