Make number of week rows dynamic, 5 vs. 6 week rows

[Timan123]

I see in daysTemplate.js that 42 day cells visible on the calendar month is hardcoded, 6 rows * 7 day weeks = 42. I would like to see it be dynamic, only 35 day cells (or 5 * 6) in months that are fully contained within 5 weeks. My designer doesn't like that full weeks in a different month are rendered for the month.

Here is a stackoverflow discussing something similar in a different package.
