The verb "hacer" (to do or make literally) can be used in various ways to talk about the passage of time. We use "hacer" to describe how long ago something happened or how long you have been doing something. You can also use "hacer" to describe past actions that were interrupted by another action. For example: Hace 1 año que tuve el accidente de coche (or Tuve el accidente de coche hace dos años) - I had the car accident 1 year ago / Hace 2 años que trabajo para esta empresa - I have worked for this company for 2 years / Hacía tiempo que no veía a Laura cuando me la encontré en la cafeteria - I hadn't seen Laura for a long time when I met her in the cafeteria.
