BizTimeCalculator exists to give small business owners, freelancers, and professionals access to powerful a free time and date calculator for freelancers, HR teams, and project managers — completely free, with no account required and no data stored on our servers.
Too many business tools are bloated, expensive, or buried behind paywalls. We believe the calculations and conversions that power good business decisions should be accessible to everyone — whether you're a solo freelancer or a growing team.
Oliver K.G. — Founder of BizTimeCalculator.com and productivity systems specialist. He has helped 200+ freelancers, contractors, and HR professionals recover lost billable hours and eliminate timesheet errors. He writes on time management, billing accuracy, and productivity.
Oliver built BizTimeCalculator as part of the Boring Factory — a collection of free, focused utility tools for business owners. No venture capital. No ads until the tool earns them. Just useful software, free to use.
We take your privacy seriously. BizTimeCalculator does not store any data you enter into the tool. All calculations happen locally in your browser. We use Google Analytics for anonymous usage statistics and Google AdSense for advertising. See our Privacy Policy for full details.
