I'm doing a deep dive right now to confirm that the calendar pages content and order matches the PDFs. The "01_Jan.PDF" file has some discrepancies I've found. For example, Jan 1 on the calendar: if you turn the page over, it starts with "1) Gather the reagents..."  but the page after Jan 1st in the PDF begins with "A) Decrypt the message with magic". I did find the content for the calendar back page in the PDF, but on the page after Jan 2. I think the PDF maker needs to redo it to be in sync with the calendar, or if the calendar is wrong, a re-print needs to happen and be sent out to everyone.

In the printed version, the resolution to the current day is on the back of the previous day. This is to prevent spoilers so you don't have to flip over the page to see the resolution.

Which should be the "correct" version to follow? The calendar version (where you look at the back side to carry out the activity) or the PDF?

Just noticed that the PDF is radically different from the printed calendar--printed on the 7th talks about a "hail of arrows" and next page is an Orc battlemaster; PDF goes on to more spellcasting and a goblin.  App seems to have the 2 main characters and app only deals with character creation/mgt.  How to proceed?  Thanks.

The App is for character management only.

You will need to create the characters you wish to play/manage via the "New Character"  button and select the character from teh list.
