The following is a dating directory I put together for myself some time ago to give a rough estimation of when each Fact File issue was released. The Fact Files were published on a roughly weekly basis from 2002-2005. The following list is based only on the few hard publication dates this wiki evidently knows for sure, which are highlighted in bold, and is meant to show approximately around what weekly period each successive issue was published. This list should not be considered a formal authority on Fact File dating, but instead may be used as a guide for helping place Fact Files in Sources lists in correct chronological order in relation to other source items. Much to my satisfaction, the dating holes filled in here actually sync up near perfectly, at least through issue 120.

For issues 121-140, extra articles originally published in the Japanese edition were added to the UK edition, ultimately extending the magazine to 140 issues until its publication end in 2005. However, as you can see, the weekly publication dates based on the first 120 issues only goes through September 2004, meaning there was some kind of considerable gap in between somewhere. I have no idea about the dating placement for issues 121-140.
