For example, if that were the case, then it would be impossible to apply the anticipating moshiach every day
in practice, because if his coming is contingent on Eliyahu hanavi announcing it three days earlier, then he can’t come today as there was no announcement two days ago….
Thanks for the reply I thought it was going to get lost.
It can be understood that the announcement that moshiach is coming can be any day,
And there are shittos that say eliyahu hanavi can announce moshiach on that day before he comes
