In chapter 15, you had Sirius escape on July 31, yet he arrived at Remus's house on July 30? Also, last chapter, you had Astraea being nearly 4 months old at the end of July yet she was born in early May. That would make her nearly 3 months old at the time. Though I must say after looking at chapter 1 again, you are doing good at fixing your timeline inconsistencies. Good job.
P.S. What was Dudley's fate and when exactly was the invasion that made Harry aware of his Lantern powers? Was it December or January or what?
