'Worksheet1'!A2 contains a date.
If the month and day of A2 are between 0 and 7 days after today's month and day, I want B2 to equal A2. Otherwise, B2 should equal "".
Example
In other words, ignoring the years, if the month and day of A2 are within 7 days of today, I want B2 to display A2 with the year being the same as the current year. Otherwise, I want B2 to display nothing.

then just subtract the date as if it is this year and check discrepancy.
