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 Sun 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
Ego clashes are possible. Choose understanding over winning.
Give space to someone who is also under pressure.
Ask what support looks like for each of you.
Work
Obstacles show you where the plan needs changing.
Effort is required now. It pays off later.
Do not take a setback as a verdict.
Mood
Restless or frustrated at times. Channel it into action.
Rest matters more than usual this week.
Remember why you started.
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.
