WEEK_ROWS_IN_MONTH constant

int const WEEK_ROWS_IN_MONTH

Months can have up to 6 partial weeks. We also may need space for a title, but a 6-week month will always have an inline title. (Proof: Longest month is 31 days. 28 of those days will appear in the middle 4 weeks, leaving 3 days. To reach 6 weeks, there must be at least 1 day before and after the middle 4 weeks. Therefore there can be at most 2 days in the first week, giving enough space for an inline title.)

Implementation

static const WEEK_ROWS_IN_MONTH = 6;
