What is a 75th anniversary or birthday called?
What is the difference between a birthday and a birth anniversary Can you call the celebration of a birthday a birth anniversary or should it better be called a birthday?
In the UK, the 70th anniversary is traditionally called the Platinum Anniversary. Neither the US traditional list nor US modern usage have a color or gem associated with the 70th anniversary. Diamond and gold are used for the 75th anniversary in the US, but the UK traditional list has nothing for 75.
