Difference between ”が”はじまる and　”は”はじまる


I asked my teacher why is "が”はじまる instead of ”は”はじまる. She said "が” is always
put before はじまる. But she said there are circumstances that ”は” is put before
はじまる too. She said there are rules meanwhile couldn't clarify. Anyone can
explain this? Many thanks!




が is used to report news or information recently discovered ("neutral
description ga"). So ～が始まる is used when you want to tell a certain event will
start now.

は is used to describe a general fact. ～は始まる is used to describe a fact that's
related to the beginning of something. The described "fact" has nothing to do
with what's happening in front of you.

>   * セサミストリート **が** 始まります。 Sesami Street starts (now).
>   * セサミストリート **は** 日曜日の朝9時に始まります。 Sesami Street starts at 9:00 Sunday
> morning.
>   * × セサミストリートは始まります。 (Makes no sense; sounds like "× Sesami Street is a
> thing that starts.")
