Month at a Glance
May is the month where the calendar stops pretending winter is a recent memory. Mother's Day anchors the second Sunday, Memorial Day closes out the last Monday, and graduation ceremonies pack the three weeks in between. It's also Mental Health Awareness Month in the US and the point in the year where 'let's do something this weekend' stops being a punchline.
