As a subject matter expert in calendar studies, I can provide you with an accurate answer to your question about the number of Thursdays in the year 2017.
First, let's establish the type of year 2017 is. It is not a leap year, which means it has 365 days. A leap year has 366 days and occurs every four years to account for the extra time it takes the Earth to orbit the Sun. Since 2017 is not divisible by 4, it is a common year.
Now, let's consider the weekly cycle. There are 52 full weeks in a year, which accounts for 364 days. The remaining day in 2017, which is the 365th day, will fall on a Wednesday. This means that the first day of the year, January 1st, 2017, was a Sunday.
To determine the number of Thursdays, we can start counting from the first Thursday of the year and continue until the end of the year. Since there are 52 full weeks, we would have 52 Thursdays. However, we must also consider the extra day, which will be the 365th day of the year. Since January 1st was a Sunday, the 365th day will be a Wednesday, and the day before, December 31st, will be a Thursday.
So, including the last Thursday of the year, we have:
52 (full weeks) + 1 (the extra Thursday at the end of the year) =
53 Thursdays in the year 2017.
