We've had a few complaints from people in regard to how the calendar works on their mobile device or ipad, when they are looking to mark books read and select the date.
Unfortunately, this is functionality built into all mobile devices however we believe most people aren't aware of how they work.
You don't have to scroll through various years just to add that book you read back in 2004.
When you click the dropdown for "Date Read", at the very top left it lists the current year.
Click that, and you can change the year to whatever you need. That's a lot faster process then cycling through many years!
