Yes, I looked up one of the chronologies, it lacks dates in many cases but goes of days mentioned versus mention of holidays, but Taisham first, basically January although more accurately the winter solistice or December 20-22 was Rand's b-day.

Each month is 28 days, 13 months, So from Taisham 1 to Saven 10 (today) is 150 days. Basically mid-may, which is early spring in northern climes, though of course spring begin 91 days (roughly after the solstice on the equinox. So the timeline of the game should be roughly parallel to the end of new spring, maybe a little after, maybe a bit before. If we go with 59 days after the equinox, just using this year as an example, which was Mar 20, then Saven 10 should roughly parallel May 19th.
