Òzbekiston Kalendar is a free calendar application available for Android devices. This app, developed by Aksa Networks, provides information about the holidays and festivals in the Oʻzbekiston Respublikasi, complete with an alarm and widget.

The app features a user-friendly interface with a modern design and elegant colors. Users can easily navigate through the app with smooth calendar app gestures, including sliding fingers to move between months and clicking on the month name to see the full list of Uzbekistan's holidays and events for that month.

One of the app's unique features is that it plays the Òzbekiston National Anthem, "O'zbekiston Respublikasining Davlat Madhiyasi," as an alarm. Users can set alarms for one-time, weekly, monthly, or yearly events. The app also allows users to choose between Monday or Sunday as the start of the week.
