Formula for Wednesdays & Sundays in 2021

Hi I am looking a way to bring in dates for 2021 in an excel sheet. I need only Sundays and Wednesdays though. Sunday to wednesday is then three days and wednesday to sunday is 4 days. I can take one cell and add 3 and then the wednesday cell and add 4 but is there an easier way? Sorry I am not so good with excel. I have added a pic to try to show what I mean. So. is Sunday and Mi. is Wednesday. I am in Germany

Thanks in advance

Please take a moment to amend your thread title. Make sure that the title properly explains your request. Your title should be explicit and not be generic (this includes function names used without an indication of what you are trying to achieve).

Please see Forum Rule #1 about proper thread titles and adjust accordingly. To edit the thread title, open the original post to edit and then click on Go Advanced (bottom right) to access the area where you can edit your title.

(Note: this change is not optional. As you are new here, I have done it for you this time.)

First change 03.01.2021 to 03/01/2021 dd/mmm/yyyy
then use formula =int(b2+3)
Suppose your dates from "B2"

In A2 copied down (leave A1 blank):

=WORKDAY.INTL(MAX(A1,DATE(2021,1,1)),1,"1101110")
