I started painting the cabinets in November, and it took a good month and a half.  Mostly this was because going to school three nights a week meant I wanted to spend my weekends relaxing rather than painting.    Still, painting the cabinets was also alot of work, first they needed a good cleaning with TSP (Tri-Sodium Phosphate) to remove years of accumulated dirt and grease.  Then they got a light sanding to clean em up some more, and give the paint a key.  I also modified the far cabinet that had shelves on both sides, to only have shelves on the near side, so that the the other side could be used for brooms and mops.  With that done, I put on a coat of primer, and then two coats of paint.  If this was in a kitchen, or the cabinets were of better quality, I would also give them a coat of poly or two to protect them, but I’m not bothering with these.
