Working with .ics 👹

Concrete example: the waste disposal calendar from KELL shows the days when the bins are picked up. Sometimes those pick-ups are early, and the far safer option is put the bins out the day before. To move all the dates (except for the Schadstoffmobil!) is not trivial. Here's how we did it in towards the end of 2024:

  • Download the correct .ics from https://www.kell-gmbh.de/ (without Schadstoffmobil!)
  • Convert .ics to .tsv using https://github.com/loteoo/icsp
  • Open new .csv with LibreOffice
  • Ensure DTSTART and DTEND formats are set to date (YYYY-MM-DD) format
  • Make new DTSTART and DTENDcolumns for the adapted values
    • Formula: =<original>-1
    • Save file, close file, reopen again (to convert formula to data)\
  • Delete original DTSTART and DTEND columns
  • Make sure the DESCRIPTION and SUMMARY are informative, an emoji at the beginning of the SUMMARY is especially nice! (e.g. "🟩 Put out Biotonne"). Also, make sure that line lengths are under 75 characters long, or Nextcloud (Hub 9.0) will complain.
  • Convert .tsv to .ics
  • Copy PRODID and VERSION lines (2 & 3) from original .ics to between BEGIN:VCALENDAR and BEGIN:VEVENT (1 & 2)
  • Additionally, download just the Schadstoffmobil calendar and upload as is

Watch out that you don't have any UUID clashes! (i.e. you will need to delete existing events if same events previously uploaded.)
