What case is this ?

задание на завтра the assignment for tomorrow

What case is 'завтра' ? Genetive ??

Technically, завтра is an adverb, so it has no cases.

Actully it is from the same website!

8. "For" in setting a deadline = на + Accusative

For in the sense of a deadline or due date is expressed by на+Acc.
задание на завтра the assignment for tomorrow
мой план на лето my plan(s) for the summer

Wrong example again ???

Those are all correct examples. Russian grammar isn't so strict. If it makes you feel any better, here: It's accusative when it is possible to put whatever comes afterwards in accusative.

The problem with this website is the examples are using nouns which look the same in the nominative and accusative.

Завтра is an adverb so it has no case.
Лето is neuter, so Лето in the accusative looks the same, Лето

мой план на зиму = my plan(s) for the winter.
зиму = accusative of зима

there is a song called Надежда на завтра

Yep...

you can also consider it a time expression which is in the accusative.

Yes?
When you're learning Russian, your mind gets bent in awkward directions, like it means "for", but that is not how Russian is. It's hard to let go of the english construct. It's good to have a least a few rules. Time expressions in the accusitive.
What were you thinking??

Methinks John was just confused by the word Zaftra. He knew it had to go in the accusative, and thought Zaftra was a noun.

Well that's the thing. When talking about weeks, then its на + locative

На прошлой неделе - Last week, etc.

Well, if it is a year or smaller, use the prepositional. Anything over takes the accusative...

В прошлОМ годУ

No wrong.

В этот день, в семь часов.

Isn't it something like. Longer than a day, or shorter than a year, or a year, then you use prepositional.

В субботу

yea. A day or shorter is В +accusative

a week = На + prep

and i guess a year is в plus prep
