About TimeBar
What is this tool?
TimeBar is an informational decision-support tool that estimates limitation deadlines for common England & Wales civil claim types. It is designed for legal professionals and non-lawyers who need a clear, structured first-pass view of timing risk.
How does it work?
The calculator uses a deterministic rules engine. You choose a claim type, enter key dates, and select any relevant modifiers (for example disability, fraud/concealment, acknowledgment, or part payment). The engine applies the selected legal rules and returns an estimated deadline with a full reasoning trail in plain English.
All calculations happen in your browser. No data is sent to any server. No dates or facts you enter are stored or tracked.
Methodology
Each supported claim type is defined by a versioned rule file containing the base limitation period, the accrual/start rule, supported modifiers, and manual review triggers.
- 1Determines the start date based on the claim type’s start rule
- 2Calculates the base expiry by adding the limitation period
- 3Applies any modifier adjustments (postponement or fresh accrual)
- 4Checks for manual review triggers
- 5Returns the result with a step-by-step explanation
Date counting
TimeBar uses exclusive date counting, which is the standard convention in English law. The date of accrual itself is excluded from the limitation period. For example, if a breach occurs on 14 June 2020 with a 6-year period, the expiry is 14 June 2026.
Important limitations
This tool is not legal advice. Limitation analysis depends on the specific facts of each case, including accrual, date of knowledge, disability, concealment, and whether a court may exercise discretion to disapply a time limit. The result is only as accurate as the inputs provided and should be independently verified.
