The Electronic Prescribing (eRx) initiative is a Defense Health Agency, Pharmacy Operations Division project that allows civilian providers to electronically transmit prescriptions to military pharmacies.
More evident from high latitudes, a hemisphere's winter solstice occurs on the day with the shortest period of daylight and longest night of the year, when the sun's daily maximum elevation in the sky is at its lowest. Although the winter solstice itself lasts only a moment in time, the term sometimes refers to the day on which it occurs.
The winter solstice is the year's shortest day, but the start of winter also launches the sun's steady climb toward the long, warm days of summer. This year, the northern winter solstice occurs on Wednesday, December 21, at 5:44 a.m. ET (10:44 UTC). It happens at the same moment no matter where you live, but because we've divided Earth into 24 times zones, people around the world will observe it at 24 different times of day.
