The everyday math of work, done right
How many hours did you work this week? The hours calculator handles breaks and night shifts, and the time card calculator adds up a whole week with overtime. What does $25 an hour come to in a year? Ask the hourly to salary calculator, or check a pay rise with the raise calculator.
For deadlines, days from today finds the date 30, 60 or 90 days out, counting business days if you need to. The days between dates and date calculator handle everything else, and the military time converter turns 1700 into 5:00 PM.
Frequently asked questions

Is SundialNook free?
Yes. Every calculator is free to use as often as you like. We are supported by ads, which we keep away from the calculators themselves.
Are the pay and overtime results exact?
They follow the standard rules and show every step, but they are estimates before tax and deductions. Your employer, contract or state labor department has the final word, especially for overtime exemptions.
Which holidays do the business-day counts skip?
You choose: US federal holidays, or the bank holidays in England and Wales, Scotland or Northern Ireland. UK dates come from GOV.UK. You can also skip weekends only.
