This is a general comment about many of your countdowns, expressed with this one by the coincidental fact that this is an example of time being expressed incorrectly. We neither think of, or express, five minutes or even a five minute countdown as a written expression of "05:00" (04;00, 03;00, etc.). Written, this should be "5:00", etc. To be even close to properly expressed, 05:00 would have to appear as a part of a countdown that was at least 10:00 minutes long.
