Seishun 18 dates for spring 2015?

Hello. I've not found anything in English about the spring 2015 dates for the Seishun 18 rail pass. Does anyone know if the dates have been announced and, if so, what they are? Thanks.

I believe they get announced today or tomorrow. I think they will be the usual dates (valid March 1 to April 10), although I cannot confirm yet. I am wondering whether the shinkansen extension on March 14 and its effects on the Hokuriku Line will have any impact on the Seishun 18 Kippu dates...

Updated already but still Japanese page only.

Basically no big changes until 13 Mar
After 14 Mar only Hokuriku shinkansen new open area rules will change
bc local parallel JR lines remove to as non-JR new four different rail campanies
but some special rules exist. Read after above link updated if need.

Other areas are no worry just small changes only.

Many thanks, guys.
