Formal:
* Je suis très occupé(e) aujourd'hui. (This is the most direct and literal translation.)
* J'ai beaucoup de travail aujourd'hui. (This means "I have a lot of work today.")
Informal:
* Je suis débordé(e) aujourd'hui. (This means "I'm overwhelmed today.")
* J'ai un planning chargé aujourd'hui. (This means "I have a busy schedule today.")
* Je suis plein(e) de choses à faire aujourd'hui. (This means "I have a lot of things to do today.")
Choosing the right phrase:
* Formal vs. informal: Use the formal phrases if you're talking to someone you don't know well or in a professional setting. Use the informal phrases with friends and family.
* Context: The best way to choose the right phrase is to consider the context of the conversation. If you're trying to politely decline an invitation, for example, you might use a phrase like "J'ai beaucoup de travail aujourd'hui."
Example:
* "Désolé, mais je suis très occupé(e) aujourd'hui. On pourrait se retrouver demain?" ("Sorry, but I am very busy today. Could we meet tomorrow?")
