In simple words
A transit is where a planet is in the sky now, compared with your birth chart. Here, today's Venus 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 a few days. Your Today page tells you when it is happening for you.
Love
You may want more attention than you receive. Ask kindly.
Avoid testing someone's affection.
Compromise feels easier after a pause.
Work
Wait a day before big purchases or deals.
Charm may not be enough; bring substance too.
Avoid people-pleasing at your own expense.
Mood
A little indulgent or restless.
Comfort is fine; overdoing it is not.
Choose one small treat, not five.
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.
