Telly's calendar (Posted on 2013-08-06) Difficulty: 2 of 5
Telly Monster is a friend of mine who loves triangles (and puzzles). He has asked me to make him a wooden calendar using triangles for the months. Can you design 9 wooden triangles with a letter in each corner that when rotated or rearranged will spell out all of the months of the year.

For example:

-/J\---/U\---/L\---/Y\- 
/? ?\ /? ?\ /? ?\ /? ?\

One such solution is as follows. The first 9 corners should be easy to figure out as SEPTEMBER is the nine- letter month that you need to be able to spell out.

The other letters on those blocks are:
SRV, EJH,PFO,TAD,ENL,MUO,BAI,EYG,RCU

This can be seen in the following diagram:
S E P T E M B E R
R J F A N U A Y C
V H O D L O I G U
R J _ A N U A Y _
R _ F A E U B Y R
R H _ A _ M _ _ C
R _ P A L _ I _ _
_ _ _ A – M – Y _
_ J _ _ N U _ E _
_ J _ _ L U _ Y _
S _ _ T _ U A G U
S E P T E M B E R
R _ O T E O B _ C
V E O _ N M B E R
R E _ D E M B E C
The other two solutions provided are different yet viable solutions as well.I wonder if Charlie or one of the other computer solution providers could write a program to determine all such solutions.
