CONDITIONAL FORMATTING OF DATE COLUMN

chudson002, You can use toLocaleDateString() function which returns a language sensitive representation of just the date portion of a date-time field.

For Example:

"txtContent":"=toLocaleDateString(@now)"

This will return a result like "7/19/2020". However, results may vary based on user's locale.

Hi chudson002 using the built-in formatting I don't know of a way to remove the time. But by going to advanced mode you can add your own JSON for conditional formatting on the date column. For example:

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
  "elmType": "div",
  "txtContent": "@currentField",
  "style": {
    "padding-left": "14px",
    "background-color": "=if(@currentField <= @now, '#c00000','teal')",
    "color": "white"
  }
}

will give the following result:
