Tips for a 21st birthday
- Use the Paid column on the budget page to track who has sent their share.

- Book restaurants for groups early — Friday and Saturday slots go first.
- Keep receipts on the shopping page if friends are reimbursing you.
21st birthday questions
How do I split costs with friends?
Put each shared cost on the budget page and tick the Paid column as people send their share.
Is this only for the party?
It's a full planner. Choose 12 months and add goal pages if you want it to cover your 21st year.
Can I use it on Android?
Yes. It's a PDF with links, so it works in Samsung Notes, Xodo, Noteshelf and other Android apps.
