2026 Leave Year (Jan 11, 2026 - Jan 9, 2027)
Use your earned leave with intention.
This optimizer helps federal employees turn use-or-lose hours into real breaks by finding the highest-value leave days around federal holidays, weekends, and regular days off. It prioritizes expiring leave first, favors short holiday bridges before long blocks, and shows exactly which dates create the most time away.

Federal leave accrual rates
Your annual leave accrual rate depends on your years of creditable federal service. Military service counts for non-retired veterans. Accrual rates are the same regardless of work schedule (5/8, 4/10, or 5/4/9).
| Years of Service | Hours / Pay Period | Days / Year | Hours / Year |
|---|---|---|---|
| Less than 3 years | 4 hours | 13 days | 104 hours |
| 3 to 15 years | 6 hours* | 20 days | 160 hours |
| 15+ years | 8 hours | 26 days | 208 hours |
| SES / SL / ST | 8 hours | 26 days | 208 hours |
*Employees in the 3-15 year category accrue 10 hours in the final pay period of the leave year to reach exactly 160 hours annually.
Use-or-lose rules & carryover limits
Example: use-or-lose calculation
An employee with 5 years of service (6 hours/PP accrual) has 220 hours on November 15, 2026. The leave year ends January 9, 2027 with 4 remaining pay periods.
| Pay Period | Starting Balance | Accrual | Ending Balance |
|---|---|---|---|
| PP 23 (Nov 22) | 220 hours | +6 hours | 226 hours |
| PP 24 (Dec 6) | 226 hours | +6 hours | 232 hours |
| PP 25 (Dec 20) | 232 hours | +6 hours | 238 hours |
| PP 26 (Jan 3) | 238 hours | +10 hours* | 248 hours |
Projected balance: 248 hours | Carryover limit: 240 hours
Use-or-lose: 8 hours (1 day) -- Take at least 1 day of leave before January 9, 2027 to avoid forfeiture. Best dates: December 26 (after Christmas) or January 2 (after New Year's).
*Final pay period of leave year: 3-15 year employees accrue 10 hours instead of 6.
2026 holiday optimization strategies
2026 has excellent opportunities to maximize time off. Here are the highest-efficiency combinations:
Independence Day Week: 5 Days Off, 2 Leave Days
July 4th falls on Saturday, so the federal holiday is observed Friday, July 3rd.
2.5x efficiency: 16 hours of leave = 5 consecutive days off
Thanksgiving Week: 9 Days Off, 3-4 Leave Days
Combine Thanksgiving Thursday with Mon-Wed off for a full 9 days.
2.25x efficiency: 32 hours of leave = 9 consecutive days off
*Some agencies grant Black Friday as administrative leave (24 hours / 3 days in that case)
Christmas to New Year's: 10 Days Off, 4 Leave Days
Christmas falls on Friday, New Year's Day on the following Thursday.
Dec 25 (Fri) Christmas → Dec 26-27 Weekend → Dec 28-31 4 LEAVE DAYS → Jan 1 New Year's → Jan 2-3 Weekend
2.5x efficiency: 32 hours of leave = 10 consecutive days off
Sick leave retirement credit
Unlike annual leave (which is paid out at separation), unused sick leave converts to additional service credit at retirement. This can significantly increase your FERS pension.
Only complete 30-day months count. Days beyond a full month are dropped.

Compressed schedule impact
Your work schedule doesn't affect accrual rate, but it does affect how quickly you use leave when taking full days off:
| Schedule | Hours / Leave Day | Days to Use 240 Hours |
|---|---|---|
| 5/8 (Standard) | 8 hours | 30 days |
| 5/4/9 (9-hour days) | 9 hours | 26.7 days |
| 4/10 | 10 hours | 24 days |
Key insight: Employees on compressed schedules burn through annual leave faster when taking full days off. This is critical for use-or-lose planning. Taking half-days on longer workdays can stretch your leave balance further.
