About Zyrone.tech

Zyrone.tech is a small, independent collection of free age calculators built around one idea: age calculations should be exact, fast and private.

Professionals — speech-language pathologists, school psychologists, teachers — need a chronological age they can trust before scoring a single assessment item. Parents need clear answers about school cutoffs and preemie milestones. Yet many online calculators are cluttered, assume every month has 30 days, or quietly disappear. We built Zyrone.tech to be the reliable alternative.

Our principles

• Accuracy first. Every tool uses the professional borrowing method with true month lengths and leap-year handling.
• Privacy by design. All calculations run in your browser. No dates you enter are stored, transmitted or logged.
• Free, always. No sign-ups, no paywalls.

A note on scope

Our tools are reference utilities, not professional advice. For clinical, legal or admissions decisions, verify dates against official records and follow the relevant manual, regulation or professional guidance.
