Frequently asked questions

How do you count the days?

The tool counts calendar days from your date of birth to today using date arithmetic. This stays exact across leap years and daylight-saving changes, unlike multiplying years by 365.

Why is my day count different from years × 365?

A year averages 365.25 days because of leap years. The tool walks the real calendar instead of multiplying, so the day count is exact.

Is the live seconds counter accurate?

Seconds tick in real time from your device clock, so accuracy depends on your system time being set correctly.

What is the life-in-weeks chart?

It is a grid where each square is a single week of a long human life. The filled squares are the weeks you have already lived, and you can set the total length yourself.
