Svátky is a free Android app that displays name days according to your contacts. It is a useful application for those who want to know which of their contacts have a name day. The app provides a list of Czech and Slovak name days and allows you to search by name.

The app offers notifications to remind you of upcoming name days, and you can customize the theme of the app to your liking. Additionally, Svátky has a widget feature that includes a 1x1 warning icon, a widget with a list of holidays, and a widget that displays the feast of the day. Since version 3.0, the app is adjustable to any size, and you can change the font color and size according to your preference.

The free version of Svátky includes advertising and does not provide a list of names with information on origin, gender, home address, reach significance horoscope (for SK), or favorite color (for SK). It also does not include statistics on the number of people using the name (for the time being the Czech Republic, the statistics I found SK), sayings, or birthdays. If you want these features, you should try the paid version.
