I've been using Rainlendar for 2 years or so, and I think it's great.
I mostly use it to keep track every week of the airing dates of the american and english TV shows (I'm French).
Although, I have a pretty annoying problem. Some tasks show up the day before the day I chose.
And the strangest thing is that the first time the tasks showed up, it was fine, at the correct date, but the next week they showed up one day early.
Some tasks work just fine, some others don't. But I created them all in the exact same way.
I attach one of the task that shows up too early.
Before creating this topic, I of course searched the forum. I found one topic
where someone seemed to have the same problem (or at least a similar problem).
And yes, I stole the name of the topic !
It has been replied that the problem was found and would be fixed in the next build. I am using the most recent version of Rainlendar (2.7).
