Birthdays are a time to celebrate with family and friends. But if you're on a tight budget, that doesn't mean you can't have a good time!

Here are ten birthday ideas that won't break the bank:

1. Have a picnic in the park - Birthdays are all about celebrating with the people you love, so why not have a picnic in the park? Just pack some sandwiches, snacks, and drinks, and you're good to go. If you want to get really fancy, you can even make your own birthday cake. Just be sure to pack some plates and utensils so you can enjoy your picnic to the fullest.

2. Have a movie marathon - If you're more of a homebody, why not have a movie marathon with your friends or family? You can either rent some movies from your local video store or stream them online. And don't forget the popcorn! 

3. Go for a hike - If you're looking for something active, why not go for a hike? It's the perfect opportunity to get some fresh air and take in some stunning scenery. Just be sure to wear comfortable shoes and bring along some water to stay hydrated. 

4. Make your own dinner - Going out to eat can be expensive, so why not stay in and make your own dinner? You can either cook your favorite dish or try something new. Either way, it'll be a night to remember. 

5. Browse your local thrift store - If you're looking for a unique gift, why not browse your local thrift store? You never know what treasures you might find. And who knows? Maybe you'll even find something for yourself!

6. Go bowling - Bowling is always a fun activity and most alleys offer package deals that include food and drinks for a discounted price. This is a great option for older children who want something more than just cake and ice cream.

7. Visit a nearby city - If you live in a small town, take a day trip to the nearest big city. There's always something new to see and do in a new place. Plus, it's a great opportunity to people watch!

8. Go stargazing - Head out to a dark spot away from city lights, and spend some time admiring the night sky. If you're lucky, you might even see a shooting star!

9. Visit a dollar store - Dollar stores have everything you need to throw a fun birthday party. You can find plates, cups, decorations, party favors, and even games and activities all for just a few dollars.

10. Make homemade pizzas - Get the kids involved in making their own pizzas for a fun and unique birthday activity. You can either make the dough from scratch or buy it pre-made to save time. Then let each child top their pizza with their favorite toppings.

I hope these ideas help you plan the perfect birthday on a budget. Remember, it's not about how much money you spend; it's about spending time with the people you love doing things that make you happy. 

So go out there and have some fun!
