Back in the day I used AutoCalendar to check My work calendar whether I had An All Day Event named 'Homeworking' planned for the next day. Then based on that it changed the alarm. I tried doing this using AutoWeb (since I don't want to install yet another app) and the Google Calendar API. But i cant seem to find out how to do it. I Already Used 'List calendar' to get the calendar ID. Then I'm using 'List events' for that specific calendar ID. I'm having a hard time figuring out which variables to use and which filter to apply to get the all day events occurring tomorrow. Any advice ?
