When do you open the wedding gifts?

Definitely open and send a thank you card ASAP! If they didn't want you to have the gift yet, they wouldn't have sent it to you. Last thing you want is someone wondering where their thank you card is

Open it and send a thank you right away. You don't want to wait to open it just in case it is the wrong item, it is broken or otherwise needs to be returned. You also want to let your guest know that you did receive it. If it gets shipped straight to you sometimes the gift giver doesn't know if it has been delivered.

Agreed with everything said here.

You can also send a thank you that isn't an official "wedding" thank you. I think the gift giver should know you got your item safely, so you need to acknowledge it has been received. You can follow up with a more formal wedding thank you at a later date if you want to, such as after the wedding, when the thank you on official stationary can be sent thanking them for attending.

You should open it and send the thank you card as soon as possible. On most registries now days, the buyer has the option to have the gift shipped directly to you so you will probably start getting several between now and the wedding to keep your guests from lugging gifts in and to keep you from lugging gifts home lol plus you can start using your goodies right away!

We opened gifts, and sent thank you cards, as they came in. It definitely saves from having to keep track by the time your wedding is over.
