Is there a Photos extension that would enable me to use the 'Big Date' Theme like iPhoto used to have?

[ToddJ]

I make a calendar every year for my mom and i used to use iPhoto back in the day to make it with iPhoto. Now what i do is make the calendar in iPhoto in my REALLY old MacBook Pro (2008) and then use the PDF to send to Mimeo to make the calendar. However, my MacBook Pro is SOOOOOOO slow and would rather use one of the extensions on Photos to make it but i can't find a calendar app that utilizes the Big Date font (my mom is elderly.) Is there an extension that I don't know about that utilizes the Big Date font for the calendar?
