Import the google calendar for DS4 events and bins with the following link (don't download, but copy/paste the link in your calendar app!)

Link calendar

Copy this:

https://calendar.google.com/calendar/ical/ds4calendar%40gmail.com/public/basic.ics

You'll find 12UB's, trash bin schedules, events on there and they are automatically adjusted by the house calendar manager. The ds4 calendar will also always be logged on to on the GR pc, so you can also check it there.
