Quick answers for common planning goals, ranked from the same rota search.
Use the whole leave budget efficiently
The optimiser selects non-overlapping breaks to maximise total calendar days away within the leave budget you entered.
Plan around the full eight-day cycle
The preset uses two day shifts, two night shifts and four rostered-off days. For leave optimisation, day and night duties both count as rostered work shifts, but the result labels them separately so you can check the suggested dates against your rota.
Why the anchor date matters
Two people on the same 2D/2N/4-off system can be on different cycle positions. Entering a known first day-shift date anchors the repeating pattern so the suggestions correspond to your own planning year rather than a generic example.
Night-shift caution
The planner is date-based. If your employer treats an overnight duty, reporting time or leave deduction differently from the calendar date shown, use the employer's roster system as the source of truth.
Use the leave balance and rota dates supplied by your employer. Work Decisions UK only models the calendar pattern you enter and does not determine employment rights, leave deductions or approval.
2D / 2N / 4O cycle reference
| Position | 1 | 2 | 3 | 4 | 5–8 |
|---|---|---|---|---|---|
| Duty | Day | Day | Night | Night | Off |
The cycle contains four rostered work positions and four off positions. For leave-block searching both day and night duties count as work, while the duty label is retained so you can verify suggested dates against your actual roster.
Optimise your actual dates
The useful part is not a generic example calendar. Your position within the repeating cycle changes the best leave dates, so the optimiser asks for one date you know is day 1 of your cycle and generates the planning year from that anchor.
Example: bridge two four-day rest blocks across day and night duties
Assume 1 January 2027 is the first day shift in a DDNNOOOO cycle. The roster then places day shifts on 9–10 January, night shifts on 11–12 January and rostered-off days on both sides of that four-duty block.
| Dates | Roster position | Example action |
|---|---|---|
| 5–8 January | Rostered off | No leave required |
| 9–10 January | Day shifts | Book as leave |
| 11–12 January | Night shifts | Book as leave and verify overnight-date treatment |
| 13–16 January | Rostered off | No leave required |
On those stated assumptions, four leave shifts connect the two rest blocks into 12 calendar days away, from 5 to 16 January. The numerical result matches a four-on/four-off work/off pattern, but retaining the day and night labels matters when you compare the suggested dates with an employer roster.
Why night shifts require an extra check
An employer may label an overnight duty by its report date, finish date or a local roster convention. This planner assigns each duty to one calendar position and cannot determine how your employer deducts leave. Confirm the dates and units before making a request.
