UpdateJuly 1, 2026
- Ever wondered how many days have been passed since you were born 👶 or since you've been married 👰?
- How many weeks are left until your next vacation 🏝 starts or a project must be finished 👨💻?
- Are you counting the days since you've started your diet 🍏, daily workout 🏄♀️ or quit smoking 🚭?
- How many hours until a highly anticipated movie 🦖 opens or the new awesome video game 🕹 will be released?
Yonks (British slang for "a long time" 🇬🇧) helps you to keep track of all of these dates and their notable milestones. 👌🏻 😌 🎉

The day counting app I've been looking for, for years!
A really simple to use day counter app I've been waiting for – worth every penny.
I've tested at least a dozen
day counters, none of which are as beautiful or as well thought out as Yonks.
This is such an amazingly beautiful and intuitive app.
