How do say how is your day going in french?

There are a few ways to say "How is your day going?" in French, depending on the level of formality and the context:

Formal:

* Comment allez-vous aujourd'hui? (This is the most formal option, suitable for someone you don't know well or in a professional setting)

Informal:

* Comment ça va aujourd'hui? (This is a common way to ask, suitable for friends or family)

* Comment vas-tu aujourd'hui? (This is a more personal way to ask, suitable for close friends or family)

* Ça va? (This is very informal and simply means "How are you?")

Adding a bit of politeness:

* Comment allez-vous? (This is a bit more formal than "Comment allez-vous aujourd'hui?")

* Comment vas-tu? (This is a bit more formal than "Comment vas-tu aujourd'hui?")

Using a more casual expression:

* Alors, comment ça va? (This is a casual way to say "So, how are you?")

Ultimately, the best way to say "How is your day going?" in French depends on the specific situation.
