How to compute date changes for multiple cells in a row

I'm using Excel 2007. I have a worksheet with E3 thru K3 (formatted general) that contain literals 8/11 Sun, 8/12 Mon, 8/13 Tue 8/14 Wed, 8/15 Thu, 8/16 Fri, 8/17 Sat. The 3-character days are always in the same columns. Actually, that row is repeated several rows down for 8/18 Mon thru 8/24. I copy the worksheet every 2 weeks and have to manually change those mm/dd day to different mm/dd. It's tedious, time consuming and error prone.

Is there a way to automate these changes using formulas, functions or some other "Excel magic"?

Thus far I've only used 1-digit months and 2-digit days, with leading zero for 1-digit days. Changing the column widths slightly and using 2-digits for both months and days will be fine. Months changing midweek won't be a problem. I can easily handle that manually.

I prefer changing only 1 row at a time since the row locations may change over time.

As evidence that I'm brain dead . . . I've tried multiple times to upload a sample, but can't get it to work. I choose a file, but can't upload. I've tried .xlsx and .jpg

Here's the best I can do 8/11 Sun, 8/12 Mon, 8/13 Tue, 8/14 Wed, 8/15 Thu, 8/16 Fri, 8/17 Sat

I want 8/18 Sun, 8/19 Mon, 8/20 Tue, 8/21 Wed, 8/22 Thu, 8/23 Fri, 8/24 Sat
