As @adamhholmes mentioned, if you enable “Expose parentheses in expressions” under Settings > Versions, you’ll be able to do this directly.
Another way to approach it is:
If you’re trying to create this condition in a backend workflow, you can define a parameter of type “date”, and on the front end, pass in the value using “current date/time:rounded down to day”. This allows you to compare it with the target date using a consistent format.
If you prefer to handle the condition on the front end, you can do something similar by storing the rounded current date/time in a group of type “date”.
