PTO and long weekend planner

Enter a date range, workweek and PTO budget for one break. Add employer holidays and blackout dates to compare long weekends and see the exact dates to request.

Find one continuous break within a date range. Your employer calendar stays in your browser. JavaScript is required.

How it works

Every date is classified in this order: blackout, holiday, non-workday, or workday requiring PTO. A blackout cannot be part of a break. Holidays and non-workdays cost zero PTO. Other days cost one whole PTO day. Both endpoints count; no rounding or time-zone conversion is used.

Break length = end date − start date + 1
PTO cost = count of workdays that are not holidays

For each possible start, we find the longest continuous break within budget and the selected range. Shorter choices contained in a longer affordable break are omitted. Up to ten alternatives are ranked by length, then lower PTO cost, then earlier start. Alternatives may overlap; their costs are not added together. This optimizes one break, not several trips across a year.

The optional OPM preset contains observed federal dates in calendar years 2026–2027 for a Monday–Friday schedule, including 31 December 2027 from the 2028 schedule. Other workweeks require your employer’s actual holiday dates. Federal holidays are not assumed to be paid days off at private employers.

Worked examples

Thanksgiving: one PTO day for four days off

Search 23–29 November 2026 with a Monday–Friday workweek, 26 November as an employer holiday and a one-day budget. Request 27 November for a break from 26–29 November: four days off using one PTO day.

A federal holiday without PTO

Search 3–5 July 2026 with the federal preset and a zero-day budget. OPM observes Independence Day on Friday 3 July. A Monday–Friday worker gets three consecutive days off with zero PTO.

A different workweek

For a Tuesday–Saturday schedule, no holidays and a one-day budget, search 7–10 November 2026. Request Saturday 7 November to get three days off through Monday 9 November. The equal-length 8–10 November alternative uses Tuesday instead.

Frequently asked questions

Are federal holidays included automatically?
No. The default uses only the employer dates you enter. The optional federal preset covers observed dates in calendar years 2026 and 2027 and requires a Monday–Friday workweek.
Do blackouts only block PTO requests?
No. Here a blackout means you cannot be away on that date at all. It splits a break even when the date would otherwise be a holiday or non-workday.
Can I use zero PTO days?
Yes. A zero budget finds consecutive holidays and non-workdays. A fully blocked or fully working range may have no available break.
Can I plan multiple vacations at once?
The results are alternatives for one continuous break. They can overlap, and each uses its own copy of the entered budget. Select dates yourself if splitting an annual allowance across trips.
Why does the result stop at my search boundary?
The search is inclusive and never extends outside it. Widen the range to include adjacent days. Search up to 366 days, use 0–30 whole PTO days, and enter at most 366 dates per list. Half-days and irregular shift rotations are not supported.
