You are in Eastern time.

Pacific is the time in California, and Washington, etc. Hence next to the Pacific Ocean.

There is a three hour time difference from EST to PST.

If something happens at 5:45 PST then it is 8:45 in EST.

If you have a cell phone go to tools and usually you will have a feature called world clock. Mess around with it and you might understand this a little more.

Depends on the gallery,but usually wine/cheese -finger foods. That type of thing. Newspaper promo s sent,and email announcements to mailing lists- as well as some type of actual announcement- alot of times on postcards-could be mailed to interested parties,museums,other galleries etc. People usually kind of dress up- its an excuse to- check out other gallery opening info in your local art section of area magazine, museum,happenings sections etc. Meet and greet is the thing- esp the artists involved or those who might be patrons or bring patrons of course- openings are advertising…..handouts if any would be on particular Artists and/or the Gallery and owners etc- short Bios-= see what you can find in other Galleries to get ideas—
