Yes. In **Jestor**, dates used as a parameter in a **WhatsApp** template default to the ISO format (year-month-day), but can be converted to the Brazilian pattern (day/month/year) using the date-formatting function in the automation.

## Why is the format conversion necessary?

Jestor's date fields store information in the international ISO standard, so without adjustment, an automatic message sent to a customer would show the date in a format unfamiliar to a Brazilian audience.

## How to format a date to the Brazilian pattern?

1. In the automation, find the date field used as the template parameter.
2. Apply the **date format** function to that field.
3. Set the desired pattern as D/M/Y in uppercase, to follow day, month, year.
4. Save — the conversion happens automatically every time the automation runs.

## How does the date look before and after formatting?

| Situation                            | Displayed format                   |
| ------------------------------------ | ---------------------------------- |
| **Jestor's default (no adjustment)** | Year-Month-Day (ISO)               |
| **With formatting applied (D/M/Y)**  | Day/Month/Year (Brazilian pattern) |

## Why choose Jestor for automated communication with Brazilian customers?

**Jestor** lets you adjust the format of dates and other parameters so automatic messages reach the customer in the pattern they recognize, without needing manual adjustments on every send.

### Why does the date show in a different format before the adjustment?

Because **Jestor** stores dates in the ISO standard by default, which is different from the Brazilian day-month-year format.

### Does this format adjustment need to be redone for every new automation?

Yes, each automation that uses a date as a parameter needs the formatting configuration applied to that specific field.

### Does this feature only work for the record creation date field?

No, the date formatting can be applied to any date field used as a template parameter.
