# English

One thing that I still don't exactly understand is when to use は when talking
about doing things on a certain day.

For example,

> 明日 **は** 学校に行く。

or

> 明後日 **は** 映画館に行く。

Should the は be included or excluded from these sentences? Is there a specific
situation where it should be included (besides emitting particles in a casual
situation)?

# 日本語

文に特定の日を表す語がある場合、日に「は」をつけたほうが良いかどうかがまだよくわかりません。

例として、

> 明日 **は** 学校に行く。

と

> 明後日 **は** 映画館に行く。

という文に「は」はあるほうが良いですか？ないほうが良いですか？

「は」をつけないといけない場合はありますか？（タメ口で話している場合以外）「は」をつけるべきでない場合は？

Use of は particle when talking about doing things on a certain day
`wa` is often used to state a difference between 2 cases.  
Example sakana ga suki desu. niku ha amari suki ja arimasen.

here you don't use niku ga , because you're stating a difference.

in your question, when you say kyou ha, you implicity compare to a different
time period , let's say kinou.

so it's implicitly : Kinou , nanika wo shimashita. kyou wa ... It's like : But
today I ...  
I hope this clears this up to you. Cheers.

It depends when you are speaking about something with someone. When you often
introduce a new topic or a base to speak about, you use は else you don't use
it.

When you use は, you don't have to use it again as the listener already knows
about the topic. You can speak about something related to the topic. When you
change the subject, the subject marker が is used.

One thing to keep in mind about は, is to assume it as the English equivalent
of 'as for' so when you say 明日は学校に行く, it translates to 'As for school, I will
go tomorrow' or easily 'I will go to school tomorrow'. As you are talking
about tomorrow, you can talk about meeting friends, or having lunch somewhere
or anything which you will be doing tomorrow with the one you are speaking to,
the listener knows you are talking about tomorrow, so you don't have to use は
again.

Student who skip classes often uses 明日は学校に行く...

  * 明日学校に行きます I will go to school tomorrow.
  * 明日 **も** 学校に行きます I will go to school tomorrow **too**.
  * 明日 **は** 学校に行きます I will go to school **at least** tomorrow.

I think は in that sentence implies something.

  * （少なくとも）明日は
  * （今日はできなかったけど）明日は
  * （気が変わったので）明日は
  * ...

Also, it is often used to compare with other day (e.g. today).

> 「 **今日は** 映画館に行ったから、 **明日は** 美術館に行こう」
>
> We went to the movie theater **today** , so let's go the museum
> **tomorrow**.

You can omit は if you don't need other nuance or emphasis.

It's not different from general wa/ga problems.

  1. If you simply swear an idea of going to school tomorrow, it's (私は)明日学校へ行く.
  2. When you reply to the question "What will you do tomorrow?", then 明日は….
  3. When you want to limit the scope you are referring to, 明日は…
  4. You can't add は to a noun or an adverb in a conditional clause except adverbs that represent amount or number. So, "If you go tomorrow" should be 明日行けば.
