Right now, when you enter an end-of-war-cease-fire, you go on the Throne page and it says: "Our Kingdom is at WAR with the-other-kingdom (1:1)!".
It would be helpful to say something like:
"Our Kingdom is in the end of war cease fire period against the-other-kingdom (1:1). This will end on July 9, YR9."
This helps with prepping (drafting/training/building). Also, if EOWCF period changes from age to age, it would get reflected automatically in this message.
