The Tanabata festival (also called the Star Festival) may not be relevant, but I always liked it because of the legend behind it. Feel free to skip, but heres the short version, forgive me if I screw it up:

Orihime was the daughter of the Emperor of Heaven, and her job was weaving the gods clothing. Hikoboshi (or Kengyuu) was the shepherd of the gods. They met, and fell in love, but they were so much in love they neglected their tasks. The gods clothing became tattered and their animals wandered. The Emperor became angry and banished Hikoboshi across the river of stars, making both of them miserable. He later regretted his decision, but so that they would do the jobs assigned to them he allowed them to meet just once a year, on July 7. If they do their job well a boatman will bring Orihime across the river, but if they do poorly he will make it rain so that the river is flooded. If the river is flooded a flock of birds will fly to the river and make a bridge so that they still can meet.

In astrologic terms Orihime is the star Vega, Hikoboshi is Altair, and the river is the Milky Way. They are usually on opposite sides of the Milky Way, the exception being the days of the Star Festival.

A lot of animes have a Tanabata episode because it lets them dress all the characters up in traditional clothes, go to a festival, and then watch the fireworks. Ive seen it in Ranma, Tenchi Muyo, Love Hine, a couple others& they may have one in Bleach later.
