The present continuous tense is often used to express the future.
The present continuous tense is usually used to express something that is happening right now.
e.g.
I am listening to music.
He is smoking now.
However, the present continuous tense is frequently used to express the future.
e.g.
I am cleaning my house this weekend.
I’m picking up my sister at the airport tomorrow.
I’m seeing the doctor this afternoon.
From these examples, we can see that the present continuous tense can be used to express both the present and the future. The meaning is determined by the time phrase used. If “now” or “right now” is used, it means something is happening right now; if a future time phrase is used, such as “tomorrow,” “next month,” the meaning is that something will happen or will be happening in the future. Sometimes, there is no time phrase. The time is understood in the context.
