Jitsu/nichi and getsu/gatsu

Come on guys, don’t spam a serious thread.

@sagecedar One thing that might help is to remember that question words follow the same reading as their corresponding counters. Since 五月 is ごがつ, 何月 is なんがつ. Similarly, since 十二日 is じゅうににち (you have to look after 10 for when the 日 counter is regular), 何日 is なんにち.

Other than that, I don’t have any more suggestions. I can tell you that these days I intuitively guess correctly most of the time, so I think you’ll get a feel for it over time.
