Is there nothing to look forward to next year? For all its ups and downs as a year, 2017 is a prime number. However, after midnight, the year is 2018. It is not a prime number! It is also...


*

*not a fibonacci number

*not a Bell number

*not a perfect number

*not a factorial

*not a catalan number


...and so on. The only good thing Wolfram Alpha has to say about $2018$ is that it's a divisor of $87^{18} - 1$, but I see nothing special about that.
So please help me out: What is the best thing to toast to when 2018 arrives?
 A: Well, I should say that Even What’s Special About This Number has no result for the number $2018$...
A: If there is a special name for the even numbers of the form $2p$, where $p$ is a prime number, then $2018 = 2\cdot 1009$ where $1009$ is a prime number.
The closest thing that I found is the numbers called "Safe Numbers" which is in the form of $2p+1$: https://en.wikipedia.org/wiki/Safe_prime
A: Ramanujan-Nagell equation is exponential Diophantine equation of the form $$2^n-7=x^2$$
When I searched for squares close to $2018$ I discovered that we have $$2018=45^2-7$$ and then I observed that $2018$ is a solution of Diophantine equation
$$2^n+2^{n-1}+...+2^5+2=x^2-7$$
for $n=10$ and $x=45$, which is one of myriad of possible generalizations of Ramanujan-Nagell equation.
A: We can look forward to less evil, at least. 2017 is a very evil number.  I have two proofs of this.

*Note that 5 is the number of Satan and that "derangement" is a nasty word.  How many derangements are there of 5?  44.  So 44 is evil compounded.  Also note that we had this nice pattern: 3, 5, 7, ... where all the odds were prime. What screwed it up?  9.  Evil, evil 9.  Is it any wonder that Christ died "at the 9th hour?"   So we have 9 and 44, already evil compounded.  Let's re-compound them by squaring and re-re-compound them by adding the results:


$$9^2+44^2 = 2017.$$
Chilling, no?  There's more"


*We know that gambling is evil and in craps the phrase is "7, 11 or doubles."
To get "doubles" let's take 7 twice: 7, 7, 11.  There's a multi-set of evil.  Let's super-compound them by cubing (and note that dice are cubes!) and add:


$$7^3+7^3 + 11^3 = 2017.$$
Thankfully, there are only a few hours left in this horrible year.  Let's hope we make it to 2018.
A: Every natural number is the sum of four integer squares, but 2018 is:
$$2018=(6^2)^2+(5^2)^2+(3^2)^2+(2^2)^2$$ the sum of four squares of squares.
A: Someone born that year will be having their 30 years party in $2048 = 2^{11}$ which is probably the only power-of-two any of us will live to see.
A: There is exactly one non-abelian group of order $2018$ by the Sylow-Theorems. There are exactly 2018 duplicates of this here at MSE:
Nonabelian group of order $pq $
Groups of order $pq$ are cyclic
Group of order pq is not simple
Question about soluble and cyclic groups of order pq
$\cdots $
