Timeline?

[apathy-irath.livejournal.com]

Hope that this is tagged correctly. ._.;

In any case, I was wondering if there was ever a timeline established for the events which take place over the course of the serie- and, if so, would it be possible for someone to direct me to it? Not a timeline of the history of the Code Geass world, or the time leading up to the main plot (such as when Marianne was assassinated, for example), but more something detailing how far apart events take place and the like. For example, it might be something that states that Lelouch became Zero in... say, July, and then Euphemia died in November... that sort of thing.

Apologies for the specific request, and thank you in advance~
