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 astronomical calendar, summer begins on the June equinox â the point at which the Northern Hemisphere is tilted closest to the sun and the days are at their longest during the year. The summer solstice falls on June 21 this year, but the date varies from year to year, falling as early as June 20 or as late as 22 June. Since summer (and other seasons) can begin and end on different days each year on the astronomical calendar, it can be hard to compare seasons from year to year in this way. To standardize the length and start of the seasons, in meteorology, the 12 months of the year have been split up into four, 3-month periods. Therefore, in the meteorological calendar, summer includes the months of June, July and August - always starting on 1 June and ending on 31 August.
