AgeGlide provides calculators for personal and educational purposes. We aim to provide accurate date arithmetic but cannot guarantee results in every scenario or device environment.
Not professional advice
Calculators involving age requirements, milestones, retirement or pet equivalents do not establish legal entitlement, eligibility, biological age or medical advice. Confirm important decisions against the relevant authority or qualified professional.
Calendar conventions
We generally use the Gregorian calendar, device-local dates and the rules explained on each page. Leap-day anniversaries and month-end shifts can be handled differently by institutions.
Availability and changes
The website may be updated, corrected or temporarily unavailable without notice. Do not depend on it as the sole record for time-critical obligations.
