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.

1. I'm a bit stressed out because Christmas is right around the corner and I still haven't bought presents for anyone! 

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!
