Description

Description of the new feature / enhancement

I can use Alt + Spacebar to bring up the query window, and I can do some simple addition, subtraction, multiplication and division operations in this query window, which is very convenient. So is it possible to make it support date addition and subtraction as well?
For example (yyyy-MM-dd): 2025.04.11 - 7 = 2025.04.04 2025.04.11 - 2025.04.04 = 7

Scenario when this would be used?

Obviously I'll use it to calculate date related stuff.

Supporting information

try this, guys. Date Calculator
