7. The 21st Birthday Tradition
In some English-speaking countries, the 21st birthday is known as “getting the key to the door”. The phrase comes from the time when 21 was the age of majority. The United Kingdom lowered that age to 18 in 1970, but the tradition stayed.
Families often mark the day with a speech, a cake and a gift such as a watch or jewellery. Traditions differ widely, so many people simply celebrate in their own way.

- Set a simple budget before booking anything.
- Choose a size: family meal, friends outing or larger party.
- Send invitations two to three weeks early.
