About the project

Precision time calculations without tracking walls

AgeCalc Pro was built for researchers, developers, educators, and everyday users who need high-precision time calculations without sign-up walls, opaque tracking, or server-side birth date collection.

Project Background

AgeCalc Pro combines civil calendar arithmetic, live chronometry, milestone estimation, and planetary year conversion in a single browser workspace. The goal is simple: make useful time-and-date science feel precise, transparent, and fast.

The interface borrows from precision instrument panels and astronomical mission software: dense, readable, dark, and built around numbers that update in real time.

Core Principles

Client-side

All core calculations run in your browser with vanilla JavaScript.

No logging

Birth dates and milestones are not collected by the calculation engine.

ISO 8601

Date inputs follow modern ISO-style civil calendar arithmetic.
