The **Start Time** and **End Time** in the Data Export screen, and the **Increment Date Parameters each run** checkbox in the Scheduling screen work together to determine from what period the exported data is selected.

# Setting the Start Time and End Time

Set each time in one of the following ways:

- Choose a specific date and time using the **Date/Time** picker
- Set the date and time to either:
  - *Today* - 00:00 midnight on the current date
  - *Now* - the current time and current date
- Set an offset in hours or days for either the start time or the end time.

# Incrementing the data period for scheduled exports

If you run the data export regularly, you may want to change the period each time you run the export. There are two ways to do this:

- Set the times using *Today* or *Now* and by specifying offsets in hours or days. Do not select the **Increment Date Parameters each run** checkbox.

> ℹ️ **Examples**
> ℹ️ 
> ℹ️ To export the data for the previous 7 days:
> ℹ️ 
> ℹ️ - Set the **End Time** to *Today*
> ℹ️ - Set the **Start Time** to *7 days before the end time*.
> ℹ️ - Select the **Recurring** checkbox and set the recurrence interval to whatever you prefer.
> ℹ️ 
> ℹ️ To export the data collected so far on the current day:
> ℹ️ 
> ℹ️ - Set the **Start Time** to *Today*
> ℹ️ - Set the **End Time** to *Now*.
> ℹ️ - Select the **Recurring** checkbox and set the recurrence interval to whatever you prefer.

- Set a specific date and time for either the **Start Time** or the **End Time**. You can specify the other setting using any option. Select the **Increment Date Parameters each run** checkbox so that any explicitly set dates are updated every time the task runs. These dates are incremented by the recurrence interval for the task.

> ℹ️ **Example**
> ℹ️ 
> ℹ️ To export the data monthly, for the first week of each month:
> ℹ️ 
> ℹ️ - Set the **Start Time** to the first day of the current month.
> ℹ️ - Set the **End Time** to *7 days after the Start Time*.
> ℹ️ - Select the **Recurring** checkbox and set the recurrence interval to 1 month.
> ℹ️ - Select the **Increment Date Parameters each run** checkbox. Each time the export is run, the Start Time is updated to the first of the current month and the End Time is always one week later.
