How hard is it to use technology to determine what calendar you're in? In particular, could a sensor dropped through a rift identify what year it was (assuming it ended up under the high calendar)?
Let's say normally, in the absence of a friendly Nirai, you could jury-rig some kind of sensor to do the job but it would require on the order of an hour to take its readings, rather than being instant-read.
