What is 12 AM GMT in PST?

Does the answer change during the year?

Yes. Greenwich Mean Time and Pacific Time don't change their clocks on the same dates, so over the next 12 months:

• October 14 to October 31: 12 AM GMT = 5 PM PST the previous day
• November 1 to March 13: 12 AM GMT = 4 PM PST the previous day
• March 14 to October 13: 12 AM GMT = 5 PM PST the previous day

Pacific Time switches between PST and PDT for daylight saving time; people often say PST all year.
