You can compare an event property to a specific date in a custom property by:
1. Making sure the property you’re comparing is a Date (or casting it if needed).
2. Using the standard comparison operators (<, > , <=, > =, ==, !=) in the custom property formula. [Comparison ops]
For example, if you have an event property Event Date and you want to check whether it is on or after 2024-01-01, your custom property formula could look like:
```
text
<Event Date> > = "2024-01-01T00:00:00"
LBKSYou can then wrap that in an `if` to return labels:
LBKS```
text
if(<Event Date> > = "2024-01-01T00:00:00", "On or after 2024-01-01", "Before 2024-01-01")
Custom properties support date arithmetic via datedif and also allow comparing two date properties directly (e.g., datedif(A, B, "D"), or A > B). [Custom props funcs]
