I know the end of season 11 is July 2016, beginning of season 12 is October 2016. But April found out she was pregnant in episode 11 of season 12, which took place less than 30 days after episode 09 which spanned 6 weeks. Putting episode 11 no earlier than late November 2016. But that would put Harriet's birth around June-July 2017, which means in season 13 DeLuca and Cross should no longer be interns. Unless she was already 2-3 months pregnant when she found out, either way season 13 spanned a few months so they should still be residents unless the finale took place June 30. Also around early mid season 13, April said it had been 2 months since she got married. So the only way the finale could take place early June or before is if April was heavily pregnant and didn't know or Harriet was born early (about 2 months) or 12x01 didn't actually take place in October.
Can someone help clarify the dates. I looked at the timeline page, but it doesnt show much.
