There is no universally recognized unlucky date for marriage. Many cultures and traditions have specific dates or periods they consider inauspicious, but these vary widely.
Some beliefs stem from astrology and numerology, associating certain dates with negative energy or unfavorable planetary alignments. Others are based on historical events, folklore, or superstition.
It's important to remember that these beliefs are subjective and vary across cultures and time periods.
Ultimately, the most important factor in choosing a wedding date is personal preference and the couple's individual beliefs.
