You can use the following formula to filter by a date range in a Google Sheets query:

=QUERY(A1:C9,"select * where A > date '"&TEXT(DATEVALUE("1/1/2020"),"yyyy-mm-dd")&"'")

This particular formula returns all rows in the range **A1:C9** where the date is after **1/1/2020**.

The following examples show how to use this formula in practice with the following dataset:

**Example 1: Filter Rows Before Some Date**

We can use the following formula to filter for rows where the date is before 1/10/2020:

=QUERY(A1:C17,"select * where A < date '"&TEXT(DATEVALUE("1/10/2020"),"yyyy-mm-dd")&"'")

Notice that only the rows where the date is before 1/10/2020 are returned.

**Example 2: Filter Rows After Some Date**

We can use the following formula to filter for rows where the date is after 1/10/2020:

=QUERY(A1:C17,"select * where A > date '"&TEXT(DATEVALUE("1/10/2020"),"yyyy-mm-dd")&"'")

Notice that only the rows where the date is after 1/10/2020 are returned.

**Example 3: Filter Rows Between Two Dates**

We can use the following formula to filter for rows where the date is between 1/5/2020 and 1/15/2020:

=QUERY(A1:C17,"select * where A > date '"&TEXT(DATEVALUE("1/5/2020"),"yyyy-mm-dd")&"'and A < date '"&TEXT(DATEVALUE("1/15/2020"),"yyyy-mm-dd")&"'")

Notice that only the rows where the date is between 1/5/2020 and 1/15/2020 are returned.
