Count down to the days you look forward to. Once a day has passed, see how many days it has been. Days that repeat monthly or yearly always count to the next one.

Your dates stay yours.
No account, no ads, no analytics and no tracking, and we never receive your dates. They are kept on your device and, with iCloud, in the private database of your own iCloud, which we cannot access. Deleted days stay in Recently Deleted for 30 days, so you can restore them. Questions or feedback? Email dev.sunapp24@gmail.com.
