「一週間後に解約する」 but 「一週間後での解約」, why not the same particle?


Some rough Google search shows:

> 一週間後に解約する (✓)
>
> 一週間後で解約する (☓)

but:

> 一週間後にの解約 (☓)
>
> 一週間後での解約 (✓)

If that's right, why is that discrepancy?

**和訳**

少しググった限りでは、

>
> 一週間後で解約する (☓)

に対し、

> 一週間後にの解約 (☓)

> 一週間後での解約 (◯)

なようですが、誤りでなければ、なぜこういうふうに食い違っているのですか？

**_Taking Actions at Specific Times:_**

Plain and simple, what governs the particle choice for expressing the time of
action is the **_part of speech_** that follows the particle -- nothing else.

> Use **に** with verbs:

「[一週間後]{いっしゅうかんご} **に** [解約]{かいやく}する」 = "to cancel after a week"

「5[月]{がつ} **に** [渡米]{とべい}します。」 = "I am going to the U.S. in May."

「2[年前]{ねんまえ} **に** [結婚]{けっこん}しました。」 = "I got married 2 years ago."

> Use **の** or **での** with nouns:

「一週間後 **での** （or just **の** ）解約」 = "a/the cancellation after a week"

「5月 **の** 渡米」 = "a/the/one's visit to the U.S. in May"

「2年前 **の** 結婚」 = "one's marriage 2 years ago"

> Exceptions:

Certain time words **_do not_** take a particle when followed by a verb or
verb phrase, but even with those, you need to place a 「の」 when followed by a
noun.

Those words include: [来週]{らいしゅう}、[先週]{せんしゅう}、[来年]{らいねん}, etc. = next week,
last week, next year, etc.

Correct: 「来年[行]{い}きます。」 = "I will go next year."

Incorrect: 「来年に行きます。」

Correct: 「先週の[旅行]{りょこう}」 = "one's trip last week"

**Finally, regarding combining particles:**

「にの」 is just not a possible particle combination at least in standard
Japanese.

Possible combinations include: での、への、へも、とも、のも、でも、にも, etc.

I will not give examples here as it would be off-topic. If asked as a separate
question, I might post an answer. Just mentioned it because you used 「にの」 in
「一週間後にの解約」, which is an incorrect phrase.
