SIMPLE ONE: Clearer indication of current date in new appointment view

When entering a new appointment the monthly calendar pops up so you can select which date you want for the appointment. So far so good.

The problem is the current date is nearly impossible to see…it is highlighted (see attached) in bold but it hardly jumps out. Could you make the current date another colour such as red or put a box around it perhaps?

As you’ll see in the example screenshot the 3rd May (the current day) looks almost identical to any other day. Imagine looking at this on a small smartphone display; near impossible to see. A box around the current date would be my preferred solution.
