Age Calculator
Enter your birthday and see your exact age — Notion-embeddable, saves automatically.
About this widget
The Olivtwig Age Calculator widget shows your exact age, broken down into years, months, and days, recalculated each time the page is opened. Set a birthday once and the widget remembers it across devices via a unique embed URL — no signup, no extension, no install. There's also no need to refresh manually; opening the Notion page is enough to see the latest count. Designed for personal profile pages, parent-child trackers, and personal milestone setups where 'how old, exactly?' is a meaningful question.
Why an exact-age widget in Notion
Notion can hold a birthday in a date property, but turning it into a live age display requires formulas or rollups — and even then, the result is usually just years. The Age Calculator does the whole computation natively: years + months + days, recalculated whenever the page opens. Drop it on a personal profile, a family page, or a self-tracking dashboard and the value stays accurate without any maintenance.
How the calculation works
The widget compares today's date to the birthday you set, computing whole years, then the additional months past the most recent birthday-month, then the additional days. It handles leap years and month-length differences correctly. The birthday is stored against the widget's unique URL, so reopening it on any device shows the latest age without re-entering anything.
Where to drop it
Age fits naturally on any page where someone's birthday matters.

Frequently asked questions
Is the Age Calculator widget free?
Yes. Every Olivtwig widget — including Age Calculator — is free to use, with no signup or login required.
Does my birthday get saved?
Yes. Each embedded Age widget has a unique URL, and the birthday saves to the cloud the moment you enter it. Reopening the page on any device restores the latest value.
Does it handle leap years and varying month lengths?
Yes. The widget computes years, then months past the most recent birthday-month, then remaining days, accounting for leap years and 28/29/30/31-day months correctly.
Can I track multiple people's ages?
Yes. Click Embed in the gallery for each person — each Age widget has its own URL and birthday, so you can embed several on one Notion page (e.g. a family dashboard).
Can I change the birthday later?
Yes — click the birthday inside the widget to edit it inline. The change saves to the cloud immediately.
