Macro to automate filter >= "inject todays date here"

Hi Excel gurus

Help to automate the following would be greatly appreciated.

I'm against a wall trying to create a Macro to automate a 'filter by >= "inject todays date here"

I have a workbook with a column of past - present and future dates

I's like to automate a sort feature via Macro to filter the display to today and future dates only (without drop down and manually selecting greater than or equal to then selecting todays date from list).

Can I inject todays date from system time straight into a macro as a filter criteria - if yes - How?

Thanks
