Get a "green" NWT bible. This is from the "Revised 1970 C.E." edition I am holding in my hand ...
Go to page 1461 entitled TABLE OF THE BOOKS OF THE BIBLE.
The left hand column has "Name of Book" then columns for "The Writer" "Place Written" "Writing Completed (B.C.E)" and finally "Time Covered" (B.C.E)
For the first book we have ...
Genesis - then in the last column (time covered) it says that after Genesis 1 v 2
Time covered "After 1:2 46,026 - 1657 B.C.E"
This shows that at least in 1970 that JW's had 7 creative days of 7,000 years as their theology. So that means that JW's say that after Genesis 1 v 2 the year is 46,026 BCE so if you go six creative days (6 x 7000) then:
Day 1 is 46,026 to 39,026
Day 2 is 39,026 to 32,026
Day 3 is 32,026 to 25,026
Day 4 is 25,026 to 18,026
Day 5 is 18,026 to 11,026
Now the fun starts because Mad Freddie Franz would have us believe that Adam was created at the start of Day 6 - hence 6000 years of man's existence would be -
Day 6 starts 4,026 BCE and runs until 1975 CE/AD - then 1,000 years of Christ's reign and Ta Da! 7 creative days = 49,000 years.
