In Vedic Astrology we have a rare alignment of planets happening, that hasn't happened for thousands of years. Every planet except for Venus are simultaneously in their own signs or exalted, making them tremendously powerful and auspicious. All the planets feel very comfortable in these signs, allowing them to exert their influence to their highest potential. This means this is an excellent time for launching any new projects, conceptualizing new plans or formulating goals, meeting new people, filing a lawsuit, interviewing for a job, sending out resumes, going on vacation, opening a business, and grand openings of any sort. However, Venus is getting a square from Mars and opposition from Saturn, so it's not the best time for marrying or dating or anything else Venusian.
Children born on these days will be special and will have many unusual talents. We are lucky to have a few exalted planets in our charts but to have this many is very fortunate, and an indicator of some very good karma. There are a larger percentage of old souls that will be increasing the collective consciousness of the world.
Note that I am referring to the birth chart (rasi). In the navamsha it is a little more common to have multiple planets in their own signs or exalted. The navamsha takes effect in your mid thirties or upon marriage, whichever is earlier.
