Here’s an extended look at the Marketplace Datebook for the week of June 23:

On Monday, the National Association of Realtors tells us how many existing homes were sold in May.

But hey, what about new homes? You only have to wait until Tuesday. That’s when the Commerce Department gives us those numbers.

Then of course you have to fill your house with appliances. On Wednesday the Commerce Department reports on durable goods orders, including appliances.

The House Committee on Science, Space, and Technology discusses the future of human space exploration.

Next, let’s go back in time and stand in a supermarket checkout line in Troy, Ohio. Come on, it’ll be fun. Hear that beeping sound? Forty years ago on June 26 a pack of Wrigley’s gum made history when it became the first purchase scanned using a bar code.

Thursday is National Chocolate Pudding Day. Seriously, I’m not making this up. Someone else did.

On Friday, fashion designer Vera Wang turns 65. She’s famous for those gorgeous wedding gowns.

And since it’s summer it’s time to get out of the house. “Transformers: Age of Extinction” explodes onto the big screen.
