Here are my two cents… the myth behind the story go like this… For there son, in order for him to have better luck in his marriage, better prosperity, better things in life and good Oman, he must marry the first part of the New Year. OG’s feels or believed that by having their son be-wed during first part of the New Year, but no later then June, this will prolong his marry; do better in life and better business practice. Just like the OG saying, “marry someone that is close relative to you will less your chance of divorce” because the seed does not fall far from the tree.
Family can have 2 marriages on the same year and will not bring any bad o-men to one or another. This must be their son getting married and a daughter leaving. But if two daughters gets marry on the same year, then either one or both of the daughter marriage will not last and ends up in divorce, sickness will become between the two daughters, or wealth will only come one of the girls and not the other.
In most cases, when something like this happens, the OG’s will postpone the second girls wedding until the following year to avoid all the bad o-man. The girls parents will accept and knowledge that the second daughter marriage but everything else will be postpone.
This only relate to the girls only. For the sons, is not a problem, but again, only 2 wedding per a calendar year. The third only will be postpone and it does not matter weather this the 3 son getting marry or a daughter leaving
