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.
In the United States and the rest of the northern hemisphere, the first day of the summer season is the day of the year when the Sun is farthest north (on June 20th or 21st). This day is known as the Summer Solstice. The declination of the Sun on the Summer Solstice is known as the tropic of cancer (23Â° 27'). In the southern hemisphere, winter and summer solstices are exchanged so that the Summer Solstice is the day on which the Sun is farthest south.
