Days is a free Android application developed by Seiren that allows you to manage the remaining days of important events in your life, such as the expiration date of a contract or a birthday. The app provides a simple and easy-to-use interface that allows you to set up reminders and notifications for each event.

One of the best features of Days is the ability to set up recurring events. When the remaining days are exhausted, the app will automatically renew the deadline for you, making sure that you never miss an important date. If you set an event without repetition, the app will change the number of days elapsed and display it in gray color.

Overall, Days is a useful and practical tool for anyone who wants to keep track of important events in their life. With its simple and intuitive interface, you can set up reminders and notifications in just a few clicks, ensuring that you never forget an important date again.
