Description

Thank you for the great software. I am Japanese and I use it everyday.

I have one problem in using it. The time until the meeting starts is expressed as "あと", but "あと" gives the nuance that the meeting is in progress.

Therefore, I was worried several times that the meeting had already started.

So I submit this PR.

Thank you very much for making the software.
