A wedding is always a time of joy. According to the Torah, a single person is considered a half a person until he or she gets married. Then the two single halves are joined and becoming like one person. It is a time of many preparations and coming together to build a new home and to raise another generation in the chain that has kept us a nation for the past 3,000 years. There are many laws and customs which connect the Jewish people as a nation because of the Torah which we received through Moses on Mount Sinai.
Many customs are unique to a specific community of group.
In Hebrew, the word for Groom is 'Chossan' and for Bride, 'Kallah'. There are certain dates that we can't marry for specific reasons. This includes the Sabbath, Holidays, or intermediate days of the holidays. There are also two time periods during the year that we do not marry because these periods are times of general mourning for the Jewish people. Many people get married on Lag O'mer.
