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 rising sign 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
Family or home matters may need attention at awkward times.
Be patient with people who see you differently.
Choose your battles kindly.
Work
You may feel tested by authority. Stay calm and prepared.
Rethink how you present an idea.
Hard work now builds lasting results.
Mood
A little tense. Physical activity helps.
Do not take criticism to heart.
Take care of basics: sleep, food, rest.
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.
