Real calendars. Thoughtful calculations.
Age & Dates is built around calendar-aware calculations. We do not assume every month has the same number of days or that every year is exactly 365 days. Where an exact calendar age is requested, years, months and days are calculated as calendar components. Calendar age counts complete months from the starting date, then remaining days. When a month is shorter, the date is clamped to its last day. For this tool, a 29 February birthday is observed on 28 February in a non-leap year. These are calculation conventions, not legal eligibility rules.
Simple, private-by-design tools
The calculators are designed to run in the browser. No account is required, and the basic calculation functions do not need you to submit your date of birth to a server.
Built for useful answers
Each tool focuses on a distinct task: calculating age on a date, finding a birthday, measuring days between dates, or discovering life milestones. We aim to make the result understandable as well as fast.
