When does Halo Wars 2: ATN take place?

I know Halo Wars 2’s vanilla campaign takes place in 2559, but is it late or early 2559?

Someone told me the Awakening the Nightmare campaign takes place a few months after the vanilla campaign, is this right? Will it be 2559 or 2560?

I know this DLC gives you a new Banished Campaign, 2 new Multiplayer maps, a new Firefight map, and 2 new Banished leaders, but I have no idea about where it fits on the Halo timeline.

> A: The events of Halo Wars 2: Awakening the Nightmare take place just a few months after the end of the events in Halo Wars 2. The war for control of the Ark continues to rage on and the Banished will do anything to regain the upper hand over Captain Cutter and the brave troops on board the UNSC Spirit of Fire. This willingness to risk it all, however, can have serious consequences in a place as ancient and dangerous as the Ark.

According to Phoenix Log Alice-130 Report #1, the Spirit of Fire arrives at the Ark on 03/28/2559. You can do the math from there.
