Worked example
- Example input
- 03/08/2026
- Expected result
- Monday 24 August 2026
The decision was handed down on Monday 3 August 2026 and no order sets another period.
The calculator excludes the decision date and applies the standard 21-day CPR 52.12 period. A court-directed appeal period would replace this default.
How this deadline is counted
- Period
- 21 days unless the lower court directs otherwise
- Trigger
- Date of the decision being appealed
- Direction
- Forward from the decision date
- Counting method
- 21 clear days; the decision day is excluded
All calendar days count because the period exceeds five days. A deadline ending on a court closure day moves under CPR 2.8(5).
Civil Procedure Rules Part 52. CPR 52.12(2)(b). Civil Procedure Rules source checked 06/08/2026
Exceptions and matter facts
- A court order can specify a different appeal period and must be checked first.
- Statutory appeals and particular appeal routes can use different periods.
