Midsummer's Eve is June 23rd- also called Saint John's Day.
The celebration of midsummer's Eve was from ancient times linked to the summer solstice. People believed that mid-summer plants had miraculous and healing power; so the plants were picked on this night. Bonfires were lit to protect against evil spirits;which were believed to roam freely when the sun turned southward again.
I don't know if you can say that... We hold Christmas every year, birthdays, midsummers day/eve and new year, but that's about it. And if we miss one of those holidays, we don't really care. So my answer would be no.
24th June
New Year's Eve 2015 is the last day of 2015. New Year's Eve is the day before the new year. Just like Easter Sunday 2015 or Christmas Day 2015 etc. are in 2015, New Year's Eve 2015 is also in 2015. It is not the New Year's Eve that is the eve of the start of 2015, which is where a confusion might arise leading to your question.
Eve => night before => New years eve => night before the new years day.
In the northern hemisphere it is 21 June.
Happy New Year would be proper since it's a new year not new YEARS. On the eve or the first day of the new year, wishing one a Happy New Year's Eve or Happy New Year's Day would be appropriate; however, if the eve or day isn't specified, Happy New Year is correct.
