Mission
Make time and work-hour calculations clear and private, so anyone can check a shift, a time card or a conversion without signing up.
What we build
Six calculators in three groups, all running in your browser.
- Time
- Work
- Converters
Our principles
Four commitments guide every tool.
- Useful first
- Private by default
- Explain the math
- Accessible to everyone
How we review calculators
Each tool starts from a written specification, is tested against canonical examples, and changes are recorded in the methodology revision history.
How we update this site
When a formula, default or limit changes, the calculator, its examples and the methodology change together, and the methodology revision history records the date.
What HourCalio does not do
