Anybody knows something about astrology? Why "the Jupiter–Saturn cycle is now in sextile to its most difficult period"?

Sextile indicates that the bodies are separated by about 60 degrees. Conjunction, trine (120 degree separation) and sextile are usually considered broadly unifying or harmony-creating aspects whereas opposition and square (90 degrees separation) are taken to represent tension and difficulties arising from the properties of the two bodies. The 'science' of astrology (I call it a 'science' only because its application depends on the knowledge of a set of widely accepted 'rules') is complex and whether something is beneficial, adverse, 'easy' or 'difficult' depends very much on what other aspects and influences there are. The sentence you quote - "the Jupiter–Saturn cycle is now in sextile to its most difficult period" - is actually pretty much nonsense in astrological terms. A 'cycle' denotes the whole progress of something from one state to another and back to its starting point. It cannot be said to be 'sextile' to anything (though the cycle through which two planets go may involve them being sextile to each other). The "most difficult period" would, presumably, be when the two planets were in opposition. Jupiter and Saturn , being the largest of the planets, have always been considered to be two of the most important, therefore the cycle of their aspects to each other, which takes about 20 years, has always been considered of significance.
