Hello, I'm an expert in timekeeping and calendar systems. Let's dive into the question of how many days are in the year 2017.

A standard year has 365 days, but every four years we have a leap year which has 366 days due to the addition of an extra day in February (February 29th). This is to account for the fact that it takes the Earth slightly longer than 365 days to orbit the Sun.

To determine if a year is a leap year, it must be divisible by 4. However, if the year is divisible by 100, it is not a leap year unless it is also divisible by 400. This means that the year 1900 was not a leap year, but the year 2016 was because it is divisible by 4 and not by 100, or it is divisible by 400.

Now, let's apply this to the year 2017. When we divide 2017 by 4, we get 504 with a remainder of 1. This means that 2017 is not divisible by 4 without a remainder, so it is not a leap year.

Therefore, the year 2017 has 365 days.
