Timelet - Calculate Age, Days & Date

✦ Timelet — Date & Time Calculator

Timelet is a lightweight browser extension that puts powerful date calculations at your fingertips. No need to open a separate app or website — everything works instantly from your browser toolbar.

✦ Age Finder / Age Calculator: Enter any date of birth and Timelet instantly calculates the exact age in years, months, and days. It also shows the total months, weeks, days, and hours lived — plus a countdown to the next birthday with the exact date and weekday.

✦ Between Dates: Pick any two dates and see exactly how much time lies between them — broken down into years, months, and days in a clean readable format, along with the total day count and weeks. An optional toggle lets you include the end date in the calculation.

✦ Add / Subtract: Starting from any date, add or subtract any combination of years, months, and days to instantly find the resulting date. Results show the full date, the long-form date, and the weekday — useful for deadlines, countdowns, and planning.
