If you want to list all week ending dates of a given year, for instance, to list all Saturdays of 2016, pleas do as below steps:
1. Select a blank cell, A2, and enter the year whose week ending dates you want to list. See screenshot:
2. In the cell B2, enter this formula =DATE(A2,1,1)+7-WEEKDAY(DATE(A2,1,1)), A2 is the year you want to use, press Enter key, you can see the first week ending date of the year has been displayed. See screenshot:
3. Go to C2, and enter this formula =IF(YEAR(B2+7)=$A$2,B2+7,""), and then drag autofill handle right to the cells to list all week ending dates of the year. See screenshot:
Tips:
(1) The formula =IF(YEAR(B2+7)=$A$2,B2+7,"") will return 5-digits number instead of date. Please change the 5-digits number to date with selecting and clicking Home > Number Format > Short Date.
(2) If you want to list all Fridays of the year, change formula to =DATE(A2,1,1)+7-WEEKDAY(DATE(A2,1,2))
