+# Script: popup-calendar
+
+A small script that displays the date and opens a small popup calendar with YAD when clicked.
+
+![popup-calendar](screenshots/1.png)
+
+
+## Dependencies
+
+* [`yad`](https://sourceforge.net/projects/yad-dialog/)
+* `xdotool`
+
+
+## Configuration
+
+Change these values if you want:
+
+```sh
+BAR_HEIGHT=22
+BORDER_SIZE=1
+YAD_WIDTH=222
+YAD_HEIGHT=188
+DATE="$(date +"%a %d %H:%M")"
+```
+
+If you use a tiling window manager you should enable floating for `yad-calendar`. This example is for `i3wm`:
+
+```ini
+for_window [class="Yad" title="yad-calendar"] floating enable
+```
+
+
+## Module
+
+```ini
+[module/popup-calendar]
+type = custom/script
+exec = ~/polybar-scripts/popup-calendar.sh
+interval = 5
+click-left = ~/polybar-scripts/popup-calendar.sh --popup &
+```
