In simple words
A transit is where a planet is in the sky now, compared with your birth chart. Here, today's Sun makes a square (90°) to the spot where your Moon was when you were born.
It is a time of pressure that pushes you to grow, and it lasts two or three days. Your Today page tells you when it is happening for you.
Love
Home and outside demands may clash. Choose deliberately.
A loved one might feel neglected. A small gesture helps.
Speak about feelings before they turn into irritation.
Work
Pressure at work may stir emotions. Pause before reacting.
Prioritise; not everything is urgent.
Ask for help sooner than usual.
Mood
Tired or touchy at times. Rest is wise.
Simplify your schedule where you can.
A familiar comfort can reset you.
About the square
A square sets two planets ninety degrees apart. Their needs pull against each other and ask for action. Squares feel like tension or recurring challenge, and they are also where much of our drive and achievement comes from. Working with a square, rather than against it, often builds a remarkable strength.
