Frequently Asked Questions

Before reaching out, check our FAQ page — your question may already be answered there.

Report an Error

If you spot an incorrect date or a tool that isn't working, please let us know with as much detail as possible — including your browser and device.

What to include in an error report

Tell us the page address, the date or options entered, the result you expected and the result displayed. For school holidays, public holidays or other published dates, include a link to the relevant government, school or authority source. Browser and device details help us reproduce layout or interaction problems.

Privacy when contacting us

Do not send passwords, identity documents, payment details, student records, private appointments or confidential workplace information. A simplified example is normally enough to investigate a calculation. Support messages are used to respond and diagnose the reported issue as described in our Privacy Policy.

Questions we can and cannot answer

We can explain how a tool operates, investigate technical errors and consider suggestions. We cannot provide legal, medical, financial or official education advice, confirm a government deadline, or override information issued by an authority. For consequential decisions, use our result as a guide and verify it with the responsible organisation.
