Frequently asked questions
- Does this calculate how much annual leave I have earned?
- No. Enter the leave days you can actually use. The annual leave accrual calculator provides a separate estimate of entitlement and remaining days.
- How are breaks ranked?
- Longer continuous breaks come first, then plans using fewer leave days, then earlier start dates. Up to five nonoverlapping alternatives are shown. Each is an independent plan.
- Can I plan for 2028?
- Yes. The planner has 2026, 2027 and 2028 holiday data; 2028 uses provisional KASI data before the official almanac and searches a date range of up to 366 days. Days outside your range are not added automatically.
