You can use BE + -ing to talk about something in the future. Here is the sentence pattern:
SUBJECT / BE + -ing / OBJECT / (TIME)
The (TIME) component is optional. You can include the time to give more information, or to emphasize that you’re talking about the future.
We / are going / on vacation / next week.
We / are going / on vacation.
(“next week” is informative.)
John / is playing / tennis / Saturday.
(Here, “Saturday” is not only informative, but it emphasizes the future. Without “Saturday,” we might think John is playing tennis right now.)
I / am baking / a cake / tonight.
(Also emphasizes the future to avoid confusion with the present continuous.)
