If you have any information about the 897th or 3562nd, please contact me!
The diary entry on the 897th main page is coded into an XML file and parsed according to the current date. There is a four year cycle beginning in late 1942, with the 1944-45 period repeated (because there simply aren’t four full years of diary entries). The cycle’s beginning is timed to match a current leap year with 1944, so that February 29 doesn’t have to be fudged. Not all days have unique diary entries. The cycle started fresh in 2006.
If you'd like to publish diary entries on your own web site, let me know.
