Working Time Tools Calculators for working out how long you worked: daily hours, shift lengths, breaks, weekly totals and monthly averages. Every tool handles overnight shifts and gives a decimal hours figure for payroll. Salary & Pay Tools Convert between annual salary and hourly rate, work out gross pay for a week or month, and calculate overtime at any multiplier. All figures are gross, before tax and National Insurance. Employment Tools Date and entitlement calculators for the employment relationship: notice periods, resignation dates, contract end dates, probation periods and rest breaks. General information only, never legal advice. Date & Deadline Tools Count working days between dates or add business days to a date. Bank holidays for England & Wales, Scotland and Northern Ireland are applied from an editable list, so the tools stay accurate year after year. Business Tools Tools that help with quoting, invoicing deadlines and rate setting. More business calculators — VAT, invoice totals, profit margin and freelance day rate — are planned for this section. Guides Explore helpful UK guides on working hours, salary calculations, inflation, overtime pay, employment rights and business days. Our easy-to-follow articles provide practical examples, clear explanations and useful insights to help you understand workplace and financial calculations with confidence.
