You have two reasonable choices, I think:</p> <ol> <li>The same weekday and the same calendarweek of previous year:</li> </ol> <pre tabindex="0"><code>=B3-(52+(CALENDARWEEK(B3-MONTH(B3)+6,21)&lt;&gt;CALENDARWEEK(B3-MONTH(B3)-358,21)))*7 </code></pre><p>Please note that this formula logically extends values if same calendarweek does not exist.</p> <ol start="2"> <li>Closest same weekday to direct day of source year:</li> </ol> <pre tabindex="0"><code>=DATE(F$2,MONTH(B3),DAY(B3))+CHOOSE(WEEKDAY(B3)-WEEKDAY(DATE(F$2,MONTH(B3),DAY(B3)))+7,1,2,3,-1,-2,-1,0,1,2,3,-3,-2,-1) </code></pre><p><img src="https://www.sulprobil.de/Previous_Year_same_Weekday_and_Calendarweek.png" alt="Previous_Year_same_Weekday_and_Calendarweek"></p> <p><strong>Note</strong>: A comprehensive documentation of my Excel implementations can be found in <a href="https://www.sulprobil.de/excel_vba_a_collection_en/" title="Excel VBA A Collection">Excel VBA A Collection</a>.</p>
