Edit generate-calendar.py to set start_date
A custom event looks like:
newyear = Event(
name = "Happy new year everyone!",
begin = "2020-12-27 00:00:00",
end = "2021-01-01 23:59:59",
transparent = True
)
newyear.make_all_day()This generates rt-rota.ics
Commit rt-rota.ics and push, people who have subscribed to the raw githubcontent.com address will receive the update.
post-to-slack.py takes two arguments, --calendar [file] and --webhook. The webhook can be generated in Slack.
