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.
Several islands off the Asian continental mainland are also in the Southern Hemisphere. Due to the tilt of Earth's rotation relative to the Sun and the ecliptic plane, summer is from December to March and winter is from June to September.outhern Hemisphere climates tend to be slightly milder than those at similar latitudes in the Northern Hemisphere, except in the Antarctic which is colder than the Arctic. This is because the Southern Hemisphere has significantly more ocean and much less land; water heats up and cools down more slowly than land.
