How to plan a 30th, 40th or 50th birthday party
Milestone birthdays tend to be bigger, longer and more grown-up than a regular birthday: a venue or caterer, speeches, maybe a slideshow. Most of the work is booking early and giving the evening a shape.

Tips from the plan
- Pick the venue before the guest list grows
- Knowing whether the space holds 30 or 80 people keeps the list honest.
- Gather photos early
- A slideshow or photo wall needs contributions from friends and family. Ask three weeks out, not the night before.
- Schedule the toasts
- Put speeches after food and before cake, while everyone is still in the room and nobody is dancing yet.
- Put food first in the budget
- Food and drinks usually take nearly half. Decorations are where it's easiest to save.
Questions
When should I send invitations for a 40th birthday?
Four weeks ahead is standard. For a weekend away or a destination party, send a save-the-date two to three months out.
What's a good schedule for a milestone birthday party?
Drinks as guests arrive, food after about an hour, toasts around the two-hour mark, then cake and music.
Should a milestone birthday be a surprise?
Only if the guest of honour would enjoy one. If you're unsure, plan it openly and keep one detail, like a slideshow or a special guest, as the surprise.
