hi, how about a simplified version of this app? set a collection day for a specific user from monday to friday 'bin day' then apply the following rule: first week of the year = week a second week of the year = week b or maybe let user define "this week = week a" or "next week = week b" then week a = food, recycling and rubbish week b = food, recycling and garden waste so the cycle is week a , week b , week a , week b and so on, where 'week a' was first week of 2019 the variables are 'rubbish' and 'garden waste', food and recycling is collected every week. how do I write a skill that will tell me on sunday afternoon what bin to take out next week. or tell me the day before collection day which bin to take out? thank you!
