I have written about this topic in the past. I definitely experience this time of year (a time before the Tibetan new year – Losar – where things need to be reconsidered at best, and I often have to slow down to get through it with a modicum of ease). Not everyone is going to feel it though, and perhaps, depending on other astrological factors, some years will be more intense than others. So take this with a grain of salt if you like.
From February 8th until the 17th, we might encounter extra obstacles to spiritual practice, obstacles to mindfulness, or possibly even physical obstacles. It is recommended that during these ten days, we should do Vajrasattva mantras (purification), or Protector practices (Achi Chokyi Drolma or Mahakala, etc) and this is often the time of the year where Tibetans literally clean their houses. I think it is viewed as a time to move stagnant energy out. On Feb. 18th, it is a new cycle, a fresh start. So get ready ahead of time!
I would recommend this article on the topic as well: http://www.elephantjournal.com/2015/02/don-season-how-to-survive-the-next-10-days-of-chaos/
