Mapping Rogue Squadron to Stargate is difficult due to the lack of an accurate way to measure time passage across episodes of the series. We're assuming each season spans approximately one year.

Year 48 begins shortly after the end of Season 5, as the events of 'Revelations' are referenced as recent events in 'A Normal Day on Farpoint'. From this we can guess Year 49 begins shortly after the end of Season 6, and so on.

We're currently at 53:1, placing us shortly after the end of Season 10.
