The Chronicle has analyzed fourth-quarter online fundraising totals for more than 8,700 charities that process their donations through Network for Good.
Hover over any day to compare online giving totals from 2011 and 2012 and highlight a section of the lower graph to zoom in.
Giving on Monday of the first week of October 2011 is set at an indexed value of 100. So if giving on another day is at 200, that means these charities raised 100 percent more that day. This information will be updated weekly through early January.
All hours are Eastern time and indicate simultaneous giving across time zones. So 12 p.m. (which indicates giving from 12 to 1 p.m.) would also include giving from 9 to 10 a.m. Pacific time.
