Wikipedia:Articles for deletion/The International Day of Heavy Metal
My sympathies to the creator, but I can't find any |reliable sources to document any arm's-length third-party expert source that says that this is |notable, and OTADVERTISING|Wikipedia is not for promoting your invented holidays.  Like many such things, when it does "become a part of life", we'll note it here on Wikipedia -- not the other way around
