FAQ

How this task behaves

  • 01

    Can the AI change my calendar events?

    No. The AI only checks if a date is a business day. It cannot create, delete, or modify your calendar entries.

  • 02

    Does it account for regional holidays in specific Brazilian states?

    The tool checks the standard Brazilian business day logic. It does not automatically adjust for every local municipal holiday unless you provide that context.

  • 03

    Can the AI predict future business days?

    Yes. You can provide any future date and the AI will tell you if it is a business day.

  • 04

    Will the AI automatically move my scheduled meetings?

    No. The AI provides the information, but you must manually move your meetings if a holiday is detected.

  • 05

    Does it work for dates in the past?

    Yes. You can verify if a past date was a business day for auditing or historical record purposes.
