The particle は (wa)


I'm studying Japanese with みんなの日本語. In one page there are this two examples:

  * にちようびは なにを しましたか.

  * どようび なにを しましたか.

Why one of them have the particle は and the other hasn't? It's a mistake or
something?

Thank you.




It isn't a mistake. It is omitted は. We often omit a postpositional particle.

For example, 昨日(は),学校に行った, 明日どこ(へ)行く?, 何(を)食べようか?, etc.
