Our schedule had us starting duty 1315 and we were off duty at 2330. Day two; had us starting at 1400 with a planned off time of 0030. The airplane had a mechanical issue which required maintenance and we were off duty at 2055. We were then given a 10 hour turn to sit on hotel duty with a broken airplane. We were off duty on day 3; at 1530. Our day 4 brief showed a 0200 show for a 0630 go. Both pilots had been falling asleep at 0000 or later for the past few nights due to the late evening schedule we were on. There was no way to safely get adequate rest for a 0200 show. I got 2 3/4 hours of sleep and my partner reported that he had 'about 90 minutes.' We called the Company at report time and declared that we were unsafe to fly due to fatigue. Implement the fatigue awareness software that would clearly show this amount of schedule shift is unsafe. It is only a matter of time before some pilot feels pressured to take an assignment like this one and has an accident or incident with catastrophic repercussions.
