Alex Rider S3 timeline

Season 1 Timeline | Misc Timeline Notes

Some facts:

For time of year we know s3 takes place in the winter, based on dialogue from Blunt and Smithers

The trees in the background during establishing shots are just as unreliable as in s2 but during actor shots they're a mix of green and barren (most notably the cherry tree in front of the Rider house), implying late winter, probably February.

I don't know anything about the British school system, but Tom mentions having taken his GCSEs in ep1 so they're presumably on holiday from whatever comes after that (sixth form? A levels? it's Maltese to me).

Now we look at the elephant in the room. John Rider:

There are two different timestamps on the recording of the bridge exchange. 06/01/2005 and 2005-05-21. Not sure what the discrepancy means but since the latter has to be May we can assume that the former is formatted for June (as opposed to January). Also, Alex wasn't born yet in January 2005.

Alex's birthday is 13 Feb, 2005 (according to a prop from s2ep8)

Julia says that Alex was six months old, but based on the time stamp he was closer to three months old (easy mistake)

John and Helen Rider's gravestone puts their deaths in 2006 and Julia says it took her six months to track them down after the bridge exchange, so that checks out

Now in the present Mrs Jones says that it's been 17 years since Scorpia was destroyed, which would make s3 take place in early 2023

Alex is about to or just turned 17 years old

And therefore he was 15 in s1 and s2

S3 takes place over the course of nine days, which I think we can all agree is absolutely ridiculous, but that's how it works out.
