As others have pointed out, `plus` has odd behaviors for days, hours, and minutes too (DST, leap seconds). That's because dates are weird. Absolutely anyone who works with dates needs to understand this. There's no point in calling the method `plusWeird`, that's redundant. The good news is that most people actually have an intuitive understanding of dates (because we have spent our lifetimes looking at calendars) and when you are doing exotic date math ("move this to the same date next month") the default behavior of `plus` is what you want. I spent a lot of time working with Joda Time (and now java.time). I use date math functions on the regular, professionally. I found this API intuitive and ergonomic from the get-go, and well matched to the problem domain. What I see in this thread is a bunch of people with a relatively poor grasp of the problem domain trying to rethink the API.
