More on lifetime-clock

lifetime-clock.com puts time in perspective. The life clock shows how much of your life has passed and how much may remain; the age calculator gives your exact age; and there's a plain online clock too. Everything runs privately in your browser — nothing is uploaded.

Memento mori, gently

Seeing life as a filling bar — or a grid of ~4,000 weeks — is a surprisingly motivating way to value the present. Our guides cover the 'life in weeks' idea, life-expectancy figures, and using time perspective to focus on what matters.
