As followers of my eschatology know, I’ve incorrectly dated the Warning, Consolation and Miracle many times. However, my current most likely year for these events is 2022 or 2023.
I initially ruled out 2021, as the miracle occurs on a Thursday, which is not a feast day of our Lord or our Lady, we are told. So 2021 sees May 13th, one of the possible days of the month for the miracle fall on a Thursday, but also the Thursday which is a feast of the Annunciation that year. However, in many places, the feast is transferred to Sunday. And I expect that in view of the pandemic, many more places — perhaps the Church worldwide if the Pope decides so — might transfer the feast to Sunday.
On the other hand, the miracle is supposed to coincide with an uncommon event in the Church, and I don’t see any such event announced (yet).
In addition, the events of the world make it seem not entirely ready yet for the Warning. The Middle East events expected in advance of these three blessed events have not yet occurred: the alliance of the extremists into one group of nations, etc.
If it happens this year, the miracle would end the pandemic abruptly, which would be very fitting. On the other hand, since God permitted the pandemic, perhaps He sees fit that it continue, I don’t know.
