I always had this confession, Amen, I fully agree to your sentence below.
Could that be part of why 'no man knows the day', since it might NOT fall on a 'Feast Day'? Considering it is thought that the Rapture will happen when as many souls are saved as can be...since waiting too long could actually lose some people? Only God knows when that number is reached. Then, from the Rapture, the count down to when Jesus RETURNS to finish His work ON EARTH will once again, fall into line with the Fall Feasts.
