The new CalJ release 2.40 for Android brings a reshaped Widget : this component that you can place on your Home Screen between your apps icons.
The CalJ Widget shows today’s date, this week’s Parasha, and you can also resize it to make the rectangle wider: it will then display the upcoming important Zman (which changes over time during the day).
I will add, אי-ה, more interesting information later to this panel.
To place the Widget on your screen, please refer to the documentation for your device or for your Android version.
