Do you have to write the actual month out, or can you just have dates expressed like 00/00/00? And then sorta devise your own calendar of sorts and have each block of events happen in a certain “year” and if events happen near each other they can be in the same “month” but on different “days”? Not sure I’m making any sense or if it’d even work, so let’s see if this helps, taking the first block of events from the current timeline…
00/00/00 Rumpelstiltskin deserts during the Ogre Wars. Perhaps getting his limp-causing injury from this?
00/01/00 Rumpelstiltskin returns to a wife who doesn’t want to live with a coward and she leaves. Perhaps dying or being killed by Rumpelstiltskin while she tried to leave?
00/00/07 (to indicate a certain number of years have passed) A beggar offers to help Rumpelstiltskin, but he’s secretly the Dark One seeking escape from his curse.
01/00/07 Rumpelstiltskin invades the Duke’s castle to steal the dagger with Zoso’s name.
01/00/07 Rumpelstiltskin kills Zoso and takes his powers and becomes the new Dark One.
02/00/07 Rumpelstiltskin’s son, Baelfire, turns 14 and soldiers come to take him into the Ogre Wars, but Rumpelstiltskin defeats the soldiers with his new powers.
Like I said, I’m not even sure it makes sense enough to be a workable system, but figured I’d throw it out there, just in case.
Edited to add that with those dates I was going dd/mm/yy, just realised that’d confuse all you people over there who write the date the wrong way round. 😉 I guess it’d be written the American way round if you devised a system like that though.
