The Once a Year 24-Hour Chance to Give Extra! For only $25, you can provide extra support for our arts and culture groups. Each year, Give Miami distributes millions of dollars to registered non-profits. Funds contributed during the 24-period will be matched by a certain percentage. The exact percentage will be determined at the end of the day, but every gift is appreciated. All you have to do is go to https://givemiamiday.org any time on Nov 15th, select HCA from the list of organizations and the amount to give. It’s HCA’s 4th year to participate and we’ll say thanks in advance.
