As I few aircraft landing and taking off from EWR, I notice as the winds change, so do the ways that the aircraft land and take off. Is this the way it is done eveywhere...of course where possible...and what do they do under calm wind conditions? I can always tell the way the wind is blowing when I see those big birds flying south to EWR over Giants' Stadium!

Landing (and starting) into the wind is safer and more economical.
If possible, airports will use runways so that aircraft have the best possible headwind (there are exceptions, like Schiphol (AMS) where under government orders noise abatement procedures are more important than safety. This has caused accidents).

Typically, if the wind is calm, or less than 5 knots or so, the airport will transfer activities to the runway which causes the least noise pollution to the surrounding area. This may also take into account several aspects including things like who's-living-where. In Geneva for example, where there is only one runway, They will generally use runway 23 if they can, and only switch to the reciprical 05 heading when the winds require, as takeoffs on 05 make a lot of noise over some pretty nice lake-front properties, while 23 causes noise over mainly industrial areas and lower-income housing.
Other airports with multiple runways might "share the noise", with one runway being used for a while, and switching to another later in the day. I think I heard that Heathrow or CDG do something like this.

I figured as much. I live north of EWR ... and so do lots of others in Jersey. When the winds come from the north, there is a lot of noise (good noise, of course). I do believe the area south of EWR is less residential and also believe that they favor planes departing that way in calm winds. THANKS

During a calm wind day traffic flow is also a factor in determining the active runway. During those days ATL always runs east to west. The contollers can move more traffic through the airspace in that direction. It has a lot to do with the inbound flow from the northeast. In the NYC area the flow most likely has an optimum direction for a calm day.

All transport airplanes that I know of, are certificated for takeoff and landing with 10 knots tailwind... be aware that if I dont like a particular runway for takeoff because of the wind conditions, I will state so with the controller, i.e. "requesting runway xx due to weight"... and in Schiphol, their revenge will be to delay your departure 30 minutes or so...
