These are the most important dates to look in 2012:
Minor solar flares: 29 Feb or 25 March (+- 10 days) (27.2 day cycle)
Significant world event (unknown yet): 22 March (+- 12 days) (Sun in Aries)
Major earthquakes: 22 March and 28 Sept (a 189 day cycle)
Larger solar flare: 21 April or 18 May (+- 10 days) (a 190 day cycle)
Revolution/revolt makes headlines: 28 June (+- 20 days) (Jupiter in Gemini)
War: 24 November (+- 7 days) (Mars in Capricorn)
Let's see how much can we predict the future based on cycles!
The event of late March is based in transiting Sun triggering the cardinal square. The event of late June is based in tramsiting Mars triggering the cardinal square, while Jupiter enters Gemini (a pattern often seen in revolutions, but the pattern is even better in June 2013). The late November event is based in Mars entering Capricorn, while triggering the cardinal square (wars often start with Mars in Capricorn and some major outer planet aspect going on at that time; that pattern will repeat in October 2014). The solar flare events is based in cycles of 27.2 days repeating between larger solar storms, especially in multiples 6x, 7x or 8x of 27.2 days. One larger event can happen in April or May, and another in November or December this year. The 189 day cycle also seems to happen between larger earthquakes, next around 22nd March.
