Ant-Man takes place in July-August 2015.

Its epilogue takes place in December 2015. Sam is just looking for him to keep him in contact with the Avengers. The epilogue isn't set during Civil War, Sam's in hiding in Germany during all the time that Scott is being picked up by Hawkeye and Scarlet Witch.

Civil War takes place in May-June 2016.

It's 6 months between the last time we see Scott in Ant-Man and the first time we see him in Civil War. It's 10 months between him becoming Ant-Man and his participation in Civil War.

This is all on the 2015 and 2016 pages.
