What is an HMO plan? HMO means Health Maintenance Organization. HMO plans offer a wide range of healthcare services through a network of providers who agree to supply services to members. With an HMO you'll likely have coverage for a broader range of preventive healthcare services than you would through another type of plan. How does an HMO plan work? As a member of an HMO, you'll be required to choose a primary care physician (PCP).
The summer solstice in the Northern Hemisphere ranges in date from June 20 to 22. This occurs in part because of the difference between the Gregorian calendar system, which normally has 365 days, and the tropical year (how long it takes Earth to orbit the Sun once), which has about 365.242199 days.
Alternatively, when the axis tilts towards the sun, as it does between June and September, it is summer in the northern hemisphere but winter in the southern hemisphere. December 21 is called the winter solstice in the Northern Hemisphere and simultaneously the summer solstice in the Southern Hemisphere. On June 21 the solstices are reversed and summer begins in the northern hemisphere. On December 21, there are 24 hours of daylight south of the Antarctic Circle (66.5Â° south of the equator) and 24 hours of darkness north of the Arctic Circle (66.5Â° north of the equator).
