What 中二日 means?


A sentence from [こころ -
三話](https://www.aozora.gr.jp/cards/000148/files/773_14560.html#midashi130)

> それから中二日おいてちょうど三日目の午後だったと思う。

Due to 中二日, I'm uncertain about timeframe in this sentence. Based on what I
know, 中二日 means a third business day. Does it mean

> After that, three days have passed and it was afternoon of the third day.

Am I wrong?

Also, is おいて here doesn't mean 居る but 於いて which means で?




You're right, `中二日` means there're two days between today and three days from
now.

That `おいて` means "leave an interval" and different from `於いて`. `中二日おいて` means
leaving two days interval, `二日おいて` will mean the same as well.
