I stumbled upon this trying to find a way to easily add auction end times to google calendar - I vaguely remember doing this in the past, but cannot remember how or find an easy way (e.g. Chrome extension).
I am not very familiar with programming/using java script - do you know if is there a way I can using this on a windows PC?
Thanks.
