# Use Supported Date Formats

In Dataloader from MuleSoft, imports accept American (**MM/DD/YYYY**) and European (**DD/MM/YYYY**) date patterns, depending on your settings. Use a supported format in your CSV files to make sure date fields process correctly.

## Date Formats

- MM/DD/YYYY (example: 04/23/2012)

- DD/MM/YYYY (example: 23/04/2012)

- YYYY-MM-DD (example: 2012-03-25)

## Date-Time Formats

- Military time zones: MM/DD/YYYYThh\:mm:ss.mmmZ (example: 02/20/1987T12:04:12.000Z)

- Three-letter time zones with offset: MM/DD/YYYYThh\:mm:ss.mmmXXX+hh:mm (example: 02/20/1987T12:04:12.000GMT+03:00)

- Three-letter time zones: MM/DD/YYYYThh\:mm:ss.mmmXXX (example: 02/20/1987T12:04:12.000GMT)

- Three-letter time zones: YYYY-MM-DDThh\:mm:ss.mmmXXX (example: 2012-03-25T12:04:12.000GMT)
