Enter your birthday. Watch your remaining time tick, then go spend it better.
Based on your chosen life expectancy. This is a perspective toy, not a prediction. Statistically, the longer you've lived, the longer you're likely to live.
Time Left is a live countdown of your remaining time on Earth, estimated from your date of birth and a life expectancy you choose. It shows the years, days, hours, minutes and seconds ticking away in real time, along with how many weekends, summers and full moons you statistically have ahead of you. It's the ancient practice of memento mori, remember that you will die, rebuilt as a webpage.
Because vagueness is what wastes lives, not deadlines. "Someday" feels infinite; "about 2,400 weekends left" is a number you can actually feel. People who try it report the same arc: ten seconds of existential vertigo, followed by a sudden clarity about what this weekend should be for. The Stoics kept skulls on their desks for exactly this effect. This is tidier.
It's an estimate built on the life expectancy you set, and real life expectancy is a moving target: statistically, the longer you've already lived, the longer you're likely to live, and medicine keeps shifting the goalposts in your favor. So treat the clock as a lens, not a verdict. The seconds are fictional. The urgency they create is real.
