Eclipses happen when the Sun, Moon and the lunar nodes line up. They come in seasons roughly every six months, and they tend to speed things up: endings arrive sooner, beginnings arrive unannounced.
Find the house
Look at which house of your chart the eclipse falls in. That area of life is where the reshuffle happens, often over the following six months rather than on the day.
Go gently
Eclipse days are not ideal for big decisions. Watch, rest and let the picture settle.
