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.
Leave optimizer results will appear after selecting leave dates or optimizing.

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).

2026 key dates
Leave year startsJanuary 11, 2026
Schedule deadlineNovember 28, 2026
Leave year endsJanuary 9, 2027
Critical: To qualify for potential leave restoration, use-or-lose leave must be scheduled in writing by November 28, 2026. Only three conditions allow restoration: administrative error, exigency of public business, or illness. Restored leave must be used within 2 years.
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.
Use-or-lose annual leave balance example by pay period
Use-or-lose: 8 hours (1 day) -- Take at least 1 day of leave before January 9, 2027 to avoid forfeiture. Best dates: Monday, December 28, 2026 (the first workday after the Christmas weekend) or Monday, January 4, 2027 (the first workday after the New Year's weekend) -- December 26 and January 2 are both Saturdays.
*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.
Wed
Jul 1 LEAVE
Thu
Jul 2 LEAVE
Fri
Jul 3 HOLIDAY
Sat
Jul 4 Weekend
Sun
Jul 5 Weekend
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.

*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 Friday one week later.
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.
Conversion rate
Full year of credit2,087 hours
One month of credit174 hours
One day of credit~5.8 hours
Only complete 30-day months count. Days beyond a full month are dropped.
Value example
GS-13, $115,000 High-3, with 2,087 hours unused sick leave:
Additional service credit+1 year
Pension increase+$1,150/year
Over 20-year retirement$23,000+
Important: Sick leave credit increases your pension but cannot be used to meet eligibility requirements (MRA, 5/10/20/30-year thresholds). For FERS employees retiring after January 1, 2014, 100% of unused sick leave converts to credit.
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:

8 hours
30 days
5/4/9 (9-hour days)

4/10

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.
