Hello, John and Doves,
 
There may be next to no time between the sixth and seventh seals.
If so, then the Rapture could occur [Rev 7:9-17--a great multitude], followed by a seven day waiting period [about a half hour--seventh seal].  Now a half hour is seven and a half days, counting one day as one 360 day Jewish prophetical year.
So, "about a half hour" could mean about seven days.
 
If there is a seven day waiting period between the Rapture and the First Trumpet of Revelation ["hail and fire mixed with blood"--Revelation 8:7], then that period could be between Cheshvan 10 and Cheshvan 17.
 
Baruch HaShem Yeshua Ha Mashiach,
