Shift Schedule 1/3 Calculator 2026: Vacation & Holiday Planner
Plan your 2026 vacations around your 1/3 shift schedule. Features official holiday highlighting and overlap detection.
About
Balancing a "Day on, Three off" schedule with public holidays and vacation time can be tricky. You might accidentally book leave on days you were already scheduled to be off, wasting precious vacation days. Conversely, you need to know which major holidays (New Year, May Day, etc.) fall on your shift.
This tool advances the standard shift calculator by integrating a 2026 Holiday Lookup Table. It visualizes overlaps between your shifts and state holidays. The "Vacation Check" mode allows you to simulate a date range to see how many actual working shifts you would miss, helping you maximize consecutive days off with minimal vacation usage.
Formulas
The tool checks two conditions for every date:
