Utility Primer Question
Utility items are potions, tuning crystals, maintenance oils, and sharpening stones. Boosters aren’t utility items.
Utility items will also have, on your boon bar, an icon with a wrench on it after you use them, if that helps to tell them apart. Boosters all have separate icons.
I believe the equivalent primer for food will work with the birthday cake, which obviously isn’t as good as getting 24 hrs of Birthday Gift.
OTOH, I think the gifts stack in duration, i.e. 2 opened at the same time will give you 2 hrs.

That’s true, the boosters do stack in duration if you use multiple. The celebration booster (1 hour) also stacks with the birthday booster (24 hours). I used one of each once hoping they would count as two separate boosts, for the WXP.
