Use a relative date slicer and filter in Power BI Desktop
With the relative date slicer or relative date filter, you can apply time-based filters to any date column in your data model. For example, you can use the relative date slicer to show only sales data that's happened within the last 30 days (or month, calendar months, and so on). When you refresh the data, the relative time period automatically applies the appropriate relative date constraint.
Use the relative date range slicer
You can use the relative date slicer just like any other slicer. Create a slicer visual for your report and then select a date value for the Field value. In the following image, we selected the OrderDate field.
Select the slicer on your canvas and then the carat in the upper-right corner of the slicer visual. If the visual has date data, the menu will display the option for Relative.
For the relative date slicer, select Relative.
You can then select the settings.
For the first setting in the relative date slicer, you have the following choices:
The second (middle) setting in the relative date slicer lets you enter a number to define the relative date range.
The third setting lets you pick the date measurement. You have the following choices:
If you select Months from that list, and enter 2 in the middle setting, this is what will happen:
if today is July 20
the data included in visuals constrained by the slicer will show data for the previous two months
starting on May 21 and going through July 20 (today's date)
In comparison, if you selected Months (Calendar), the visuals constrained would show data from May 1 through June 30 (the last two complete calendar months).
Using the relative date range filter
You can also create a relative date range filter for your report page or your entire report. To do so, drag a date field into the Page level filters well or the Report level filters well in the Field pane:
Once there, you can change the relative date range. It's similar to how you can customize the relative date slicer. Select Relative date filtering from the Filter Type drop-down.
Once you've selected Relative date filtering, you see three sections to change, including a middle numeric box, just like the slicer.
Limitations and considerations
The following limitations and considerations currently apply to the relative date range slicer and filter.
Data models in Power BI don't include time zone info. The models can store times, but there's no indication of the time zone they're in.
The slicer and filter are always based on the time in UTC. If you set up a filter in a report and send it to a colleague in a different time zone, you'll both see the same data. Unless you are in the UTC time zone, you and your colleague must account for the time offset you’ll experience.
You can convert data captured in a local time zone to UTC using the Query Editor.
