I have receieved a request from the Netherlands, but, unfortunately, the author mentioned incorrect email address, so I post an answer here on the blog.
His question was:
What are the exact dates of the Ysyakh festival in 2012 and 2013?
The answer:
In the city of Yaktusk, Ysyakh takes place annually during the last weekend of June. So, this year it must be on June 30th and July 1st.
