Because の is doing noun-to-noun linking several times.
In this sentence:
- 雨の日 = rain day → a rainy day / a day when it rains
- 駅の前 = the front of the station / in front of the station
- 駅の前の道路 = the road in front of the station
So の often works a bit like of, or like an apostrophe-s, or like a way to turn one noun into a modifier for another noun.
You can think of it step by step:
- 雨 → rain
- 雨の日 → a rainy day
- 駅 → station
- 駅の前 → in front of the station
- 駅の前の道路 → the road in front of the station
Japanese often stacks nouns this way.
Yes, literally it is rain's day or rain day, but naturally it means:
- a rainy day
- a day when it rains
- on rainy days depending on context
In Japanese, 雨の日 is a very common expression. It does not necessarily mean the whole day is rainy in a strict sense; it just refers to days when it is raining.
