Customary mourning periods of some societies (Just because it's written doesn't mean it's true)
Hindu
4) Then there is the plight of widows. As I mentioned in my article
widow's are at the bottom of Hindu society, even below the untouchables.She cannot wear red, has to give up eating meat(if she is a non-vegitarian), she cannot wear makeup.Widow's are seen as sign of bad luck,so they are not invited in ceratin cermonies during a wedding.Family humiliation and society's torture is another thing they have to bear. In contrast if a wife dies a man is a free bird.Some even marry immediately after the customary 45 day mourning period.This is height of discrimination and cruely againt women.

27. The shorter mourning period for a spouse seems strange to us today when the loss of a spouse is, for most, emotionally and functionally the most difficult bereavement. There are many reasons behind this. For much of Jewish history, marriage was not based on ideas of love but was rather more of an economic and procreative arrangement within a society in which men and women functioned in separate realms. Practically speaking, a shorter mourning period also enabled faster remarriage in a world where single-parenting was not economically viable. Men may remarry after a month; women after three months as long as they are not pregnant (and the three months is necessary to establish this and clarify paternity).

In Tennessee, USA
A widow held the deepest level of mourning which could last 2-1/2 years or longer.
For the first year and one day, she wore only solid black clothing in public, including black jewelry. During the next nine months, white trim could be added to the black. Gold jewelry and fancy lace could be added in the following three-month period. Then during a half mourning stage, subdued colors are permitted.
If possible, widows would usually stay homebound for the first month, and were expected to wait a least a year before remarriage. Potential suitors could recognize by a widows change in dress exactly when her year and one day was up.
While on the other hand, the male widowers were only expected to wear a black armband for only a two or three month period. (Seems a little unfair, doesn’t it, ladies?)
As you can tell, some of these mourning customs are ones we still adhere to and some have fallen by the wayside. No matter how you go about it, for our own mental, physical and spiritual welfare, it is still a necessity that we complete the mourning process and only then we “shall be comforted.”
