| How to add a Relative Date Slicer in Power BI |

| How to add a Relative Date Slicer in Power BI |
In this blog
Power BI has an easily overlooked slicer option: the Relative Date slicer.
This blog will cover how to create one and explain the basic options available.

Relative Date slicers are perfect for filtering data within a specified period relative to a fixed point in time.
To use a relative date slicer, your data model needs a column with the Date data type (or the Date/Time data type).

Here, the SaleDate column stores the dates on which transactions took place.
To create a relative date slicer, first add a standard slicer visual to your report.

Insert a slicer in the usual way.
Drag the date column into the slicer's Field bucket.

By default, this creates a date range slider, allowing users to select dates between two points.
To convert the slicer into a relative date slicer, in the Format your visual pane, navigate to Slicer settings | Options | Style and choose Relative Date.

Dates can also be displayed using Tile or Vertical List slicers, although these tend to take up more space.
To use the slicer you need to set the range of dates you're interested in. The Relative Date slicer provides three comparison options for dates:
Last for previous periods
Next for future periods
This for the current period

Last is likely to be the option people use most often.
Next you can choose the type of interval. The first unit available is Days, which moves back a specified number of days.

For example, selecting Last 10 Days compares data from today back 10 days.
At the time of writing, this returns the 10 days prior to 12 June 2026.

This option includes the current date.
The Months option works in the same way, moving back the specified number of months from the current date.

12th June 2025 - 10 months = 13 August 2025
Some interval options include the word (Calendar) in their name. These options behave differently: rather than counting backwards from the current date, they return only complete periods.

May 2026 - 10 months = August 2025
If you're not in the US, beware that the Weeks (Calendar) option assumes that a week begins on Sunday.

The week is defined as Sunday to Saturday!
A useful visual that is worth the effort in this owl's opinion!
