In a literal sense, a building or physical location that is 'just around the corner' is considered to be very close. Likewise, the figurative meaning of something that is 'just/right/only' around the corner is that it's very close in time. This can refer to anything that is known to be happening soon; whether it is scheduled or is a regular event. You will hear this used in all types of situations, in contexts both social and professional.

2. I should start studying. The exams are just around the corner.

1. The deadline is just around the corner, so we cannot afford to have any setbacks at this late stage.
2. I wasn't nervous before, but now that my job interview is around the corner I am starting to feel very anxious about it!
