If 20 posts make a page and 250 posts a full five page, then divide that out by 30/31 (depending on moth) you should get 2-2.5 posts is a day. You then count up the posts, or the posts on that page and apply date with math.

The Battle of the Suez took place May 27-28 1980. Assuming we are using the time it started (around page 4) as the day, then it should be something like the second week of June.
