The 5.0.1 version of Roozegar for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The program lies within Productivity Tools, more precisely Timekeeping. This free Mac app is an intellectual property of Reza Moallemi. We recommend checking the downloaded files with any free antivirus.
From the developer:
Roozegar is a simple Persian Calendar for macOS with a tool to convert date to Jalali or Gregorian. For fast access, you can open the calendar from the status bar. The application allows you to easily switch between dates. The tool comes with a great graphical design.
