How Deadline Engine works
Calculate the date, see the rule behind it
Deadline Engine uses encoded procedural rules to calculate a date from the inputs you select. It shows the citation and working so you can check the result against the current source, any order and the facts of the matter.

What this gives you
A practical next step after the calculation
Choose a jurisdiction, procedure and trigger date to calculate a procedural deadline with the citation and calculation working visible.
Inspect the calculation
Read the stated period, citation, counting treatment and result rather than receiving an unexplained date.
Choose the next step
Keep calculating free, buy a one-off PDF record for an eligible result, or save an eligible result with Professional.
Keep the boundary visible
The calculator does not determine the correct procedure or replace review of the current law and matter facts.
Clear workflow
Check first. Then choose the right record or workflow.
The paid options follow a completed calculation. They do not replace the check that comes before a date enters a matter or diary.

Important boundary
Calculation software, not legal advice
Deadline Engine does not decide jurisdiction, interpret evidence, read a court order or party agreement, or calculate rules outside its published coverage. Check every date before it is used.

Questions answered
Frequently asked questions
Is Deadline Engine legal advice?
No. It is rule-based calculation software. You must check the current source, any order and the facts before using a calculated date.
Why is some coverage calculation-only?
A calculator can be available for self-checking without a paid server-recomputation path. Paid saving and PDF records are limited to eligible results.
