Yes - it is certainly possible but also wholly dependent on the complexity and nature of the animation you want to achieve.
For example, you could produce a 2-minute animation moving simple primitive types (such as cubes and spheres and donuts) about on the screen within a day. Alternatively, it would take months or years to fully get to grips with creating and animating interacting, realistic humanoid figures.
For simple animation it can be as easy as moving objects in the viewport and moving through the timeline and hitting I to store a keyframe. More complicated is creating a complicated model, rigging it and animating manually or using motion capture.
Start small and build up over time. Ask specific questions here when you're stuck and you'll get some great answers from this community. I'm sure in a month you can make a lot of progress.
