# Compare Date Ranges

> Set your reporting date range, enable period-over-period comparisons, and choose which columns display the comparison data.

## Setting a Date Range

The date picker is in the top-right corner of the navigation bar. Click it to change the reporting interval for the entire view.

Available presets: **Today**, **Yesterday**, **Last 3 / 7 / 14 / 30 days**, **Last 90 days**, **This month**, **Last month**, **Last 6 months**, and a fully custom calendar range.

***

## Comparing Two Periods

Inside the date picker, enable the **Compare dates** toggle. You can then select a second date range to compare against the primary one.

<Tip>
  Use **Compare dates** to spot performance shifts between periods — for example, this week vs. last week — to measure the impact of a recent creative or budget change.
</Tip>

## Choosing Which Columns Show Comparison Data

Comparison data only appears for metrics you have designated as compare columns. You configure this inside **Column Management**.

<Steps>
  <Step title="Open Column Management">
    Click the column settings icon at the bottom-left of the table.
  </Step>

  <Step title="Switch to Compare Columns">
    Click the **Compare Columns** tab at the top right of the dialog.
  </Step>

  <Step title="Select your metrics">
    Select the metrics you want to see side-by-side comparison data for (e.g., Amount Spent, Revenue, Conversions).
  </Step>

  <Step title="Save as preset">
    Click **Save as preset**.
  </Step>
</Steps>

Once set up, activating **Compare dates** in the date picker causes each selected metric to display an additional column showing the value for the comparison period — making it easy to see at a glance whether spend went up, conversions dropped, or ROI improved between the two periods.
