Notice deadline calculator.
The single most expensive failure on FIDIC and NEC projects is a missed notice. Enter the date you became aware of an event and your contract regime; this shows the deadline dates and how many days are left. Calendar days, every period editable, nothing sent anywhere.
Default 84 days — FIDIC 2017 Sub-Clause 20.2.4.

Indicative only, not legal advice. Periods are counted in calendar days (FIDIC) or calendar weeks (NEC), not working days. Particular Conditions or Contract Data routinely change every period shown — and may delete the late-notice relief at FIDIC Sub-Clause 20.2.5 — so override the defaults to match your contract. The deadline runs from the date of awareness (or, under FIDIC, the date you should have become aware), which is itself often contestable. Always issue early and take advice on a live matter.
A deadline closing in, or already passed?
If a notice window is tight or a claim has gone quiet, a senior view on the file is the cheapest insurance there is. Confidential, no obligation.
