Accurately calculating time limits is crucial but can be difficult, particularly since the introduction of the Acas early conciliation regime complicated matters. To deal with these difficulties, we have created a simple-to-use calculator.

Click the red button below to download our free calculator. If you find this useful, please also click the button to share this to your LinkedIn and/or Twitter networks.

The calculator is designed to deal with ordinary situations. It may not deal with every scenario. Where the data entered includes a leap day (29 February) the calculator may not give accurate results. The calculator should therefore be used only as a guide, and you should always take legal advice rather than placing reliance on the result generated by the calculator.
