About Matt W.

Matt W. is a New Zealand legal professional who independently publishes and maintains Working Day Calculator UK. The work focuses on the calculator's date-counting mechanics, checking cited official sources, and correcting reported errors. The articles provide general information and are not UK legal, tax, accounting, or other professional advice.

The first version was built for New Zealand, after finding that the available tools were “days between two dates” calculators — the easy direction, and the same in every country. The useful direction is the other one: given a trigger date and a set of rules, when does the deadline fall?

That question needs local rules, and New Zealand’s regional anniversary days, Mondayisation, and summer shutdown period don’t survive being generalised. The same gap turned out to exist in other common-law jurisdictions, so each country tool is built around its own rules rather than sharing one international default.

Articles by Matt W.

Guides to UK date-counting mechanics, bank-holiday calendars, and official sources. Readers remain responsible for choosing the applicable rule and trigger date.
