<p>Hi William, </p>

<p>I've tried your solution plus the code below but im getting an issue somewhere. Im running the script in batch mode and it will use the control file for the dates but id fail to see that being the issue. It could be the sum code throwing the error but i dont even get an error code up, it just runs one image and cuts off, much like it would for a missing apostrophe. Headache of all headaches this one he he. </p>

<div>I'm dealing with the same problem. Using substr() you can split day (d), month (m), and year (y), and after that this algorithm looks like works for me. Returns 0 for a Sunday and up to 6 for a Saturday.</div>

<p>Hello Users, </p>
<p><br clear="none"></p>
<p>I know this subject has been covered recently with an issue with the date for 2021, with the DAY returning '???'. Is there a suitable work around on this for both grads and opengrads users? I know there is a work around with some of you <span>implementing Zeller's congruence but alas I have no idea how to code or where to code it to. </span></p>
<p><br clear="none"></p>
<p><span>Any help on the matter would be greatly apricated. </span></p>
