Hi Eowyn, can we please have a timezone calculator on the Clean-A-Thon page? Last year I was unsure when I needed to start and finish (I think I ended up starting several hours too early)... maybe there was a timezone calculator last year, and I missed it! Actually, I see there is a link to a timezone map - thanks for that. If there is something really basic to follow for start and finish times for the major time zones, that would be wonderful.
