Frequently Asked Questions
Quick answers to help you pick the right calculator.
What is a working day?
Generally, a working day is a weekday (Monday to Friday) that is not a public or bank holiday, but each country has their own quirks — our calculators understand the quirks.
How is this different from a regular date calculator?
Unlike simple date calculators, we calculate deadline dates and notice periods (e.g. '14 working days from today'), handle sequential multi-step deadlines, and support jurisdiction-specific rules like short periods in court rules and clear days.
Can I calculate legal or court deadlines?
Yes. The UK calculator supports CPR court rules and clear-day counting. Canada handles provincial and federal court rules. Ireland supports RSC Order 122. Singapore covers ROC 2021 filing deadlines. Australia handles SOPA and court timelines. All calculators handle statutory notice periods.
Does the calculator include local holidays?
Yes. New Zealand, Australia, UK, Canada, Ireland, Singapore, and Hong Kong calculators each exclude their national and regional public holidays automatically, ensuring accurate deadline calculations.
How can I verify the results?
Every calculation includes a visual timeline showing the period, a detailed list of excluded dates (weekends, holidays), and the ability to export results to PDF for your records or to share with colleagues.
