My total time is 14 hours, 5 hour sunrise and sunset with a 4 hour mid day. The second part of the sunrise and the first part of the sunset are 3 hours. The steep part of the sunrise and sunset is about 2 hours with the colors starting and ending in 10 minute offsets. Only deep blue goes the full 2 hours, all the others are less. Sequence for on is.
