About OrbitCorner
Free, simple online tools for everyday calculations.
OrbitCorner makes free, simple online tools for everyday calculations: time and hours, dates and countdowns, quick decisions, and money. Everything runs in your browser, nothing you type is stored, and every rate or rule we use shows its source and the date we checked it.
Our Time Card Calculator, Countdown & Date Calculator, Military Time Converter and Freelancer Take-Home Calculator are live now. We add new tools regularly, starting with the questions people ask most.
Free and private
Every tool is free to use, with no account and no sign-up. The numbers you enter stay in your browser. They are not sent to us and they are not saved.
Accurate and sourced
When a tool uses a fee, a rate or a rule, it lists the official source and the date we last checked it. Read how we calculate and our editorial policy. If a number looks wrong, please tell us and we will check it.
Built by Orbit Innovation
OrbitCorner is built by Orbit Innovation, a small software team. We design, build and check every tool ourselves.
