The only way to figure out when to end your eBay auction is by planning when to start it. An auction beginning at 12:00 will end at that same time on the ending day.

eBay time is military time in the Pacific time zone. (Even after all these years, it still takes too much time to decipher eBay time without a printed chart.)

Always check your time zone and know exactly what time it is in eBay-land.
