Wedding anniversary refers to the day to commemorate the wedding after marriage. But in fact, the most celebrated and grand ceremonies are "silver wedding (25 years)" and "golden wedding (50 years)", and friends and relatives are usually invited to banquets and anniversaries. As for those who can celebrate the "diamond wedding (60 or 80 years)", it is even rarer.
