About Mercury

Mercury is your mind in motion: how you take things in, talk, text, plan and argue. It's also the planet of errands, emails and that list on the back of an envelope. When Mercury passes through a house, conversations, paperwork and second thoughts pile up there. Good for sorting things out, less good for making your mind up quickly.

About Sagittarius

Sagittarius is adventure, optimism and the search for meaning, ideally somewhere with a passport stamp. It says the honest thing and books the trip. At its best, Sagittarius makes life feel bigger and funnier than it was a minute ago. Watch for leaving before things get boring, or before they get real.

How long it lasts

Around three weeks in each sign, longer when it goes retrograde (appears to move backwards).
