Please note that I have controlled for the number of days in each month (converted to a daily average then x 30) to provide a better idea of what is going on without the confound of differences in the number of days/month. The figures are therefore slightly different from the raw numbers reported by etsy because I think it is misleading to compare periods of different durations.
Further details about how the results were obtained can be found in my earlier post here
