just wondered when FG server will get patched on a weekly time also will FG server have a new calendar since most of the monthly event don't work on it like live has
It's the same day and time as all other servers ... Tuesdays at 0700 Pacific time. It didn't happen this week because of the holiday.
In the normal course of things, Tuesday mornings (Pacific time) are patch days. We do on occasion come down at other times for emergency fixes. After a big release, it's very common to see several patches in the first couple of weeks.
