Milestones of a one-year-old baby
If you’re a new parent, knowing what milestones to look for in your baby can help you prepare for the future. Milestones are different for each baby, and may occur at different times throughout the year. The Center for Disease Control (CDC) offers a free Milestone Tracker app, complete with activities, learning tips, and a section to track doctor visits. While there are some milestones that most babies will complete by a certain age, keep in mind that each child will develop at a different rate than the next.
During the first year of life, babies are starting to understand their senses and connect objects to sounds and actions. They are becoming more aware of their surroundings and prefer to play with toys that are brightly colored and three-dimensional. In addition, they are starting to lift their head and experiment with the placement of their hands.
Leap year
A leap year is a calendar year with an additional day. The extra day is added to keep the calendar year in alignment with the seasonal and astronomical year. The calendar year is one of the most important parts of our world, and a leap year can make all the difference in your daily life.
Adding an extra day to a calendar year is an essential way to keep the Gregorian calendar accurate. The Gregorian calendar assumes the Earth completes one rotation around the sun in 365 days. In reality, the Earth takes roughly a quarter of a day to complete its full orbit around the sun. Therefore, adding a day to the calendar every four years is necessary to keep the calendar in line with the astronomical calendar.
Heliacal year
The heliacal year is the same as the tropical year of the Sun, which is the period between two successive solstices in the tropics of Cancer and Capricorn. According to the Julian calendar, this period is called the Penteteris. The heliacal rising of Sirius corresponds to a date about one month after the summer solstice.
The heliacal rising is observed in the sky around the middle of August. In ancient Egypt, it was called the “caniculer dayes,” derived from the name of the canicula, which means “little dog.” The heliacal rising of Sirius was used to compute the calendar for this period. The canicular cycle is 1,461 years long.
Vague year
In the Jewish calendar, there are twelve months, plus the thirteenth which is called Vague year. The name Vague year comes from the Latin word annus vagus, which means wandering year. It is also the name of a football player, Rhys Anthony Vague, who plays for the Kagawa Five Arrows in the ****anese B.League. The band Nouvelle Vague is another example of a band that uses the term.
The Maya calendar used a combination of mystical cycles and lunar reckonings. A typical stela inscription begins with a large introductory hieroglyph and identifies the appropriate Long Count, Sacred Round, and Vague Year. This way, each day can be fixed within six alternative timekeeping systems, and a day could be appropriately commemorated by recognizing its position within the countless dimensions of time.
Tropical year
The tropical year (also called solar year) is the length of time between the vernal equinox and the summer solstice. During this time, the Sun completes a full cycle of seasons. The seasons of the year are determined by the movements of the Sun in its orbit around the earth.
The tropical year is measured from the vernal equinox in March. It is 365 days long, 5 hours, 48 minutes, and 46 seconds in mean solar time. The tropical year is the basis for the Gregorian calendar. In the Gregorian calendar, the vernal equinox will be shifted to March 19-20.
The ecliptic and solar years are two of the most important components of the solar and tropical year. Both are important to humankind’s ability to track the seasons. The ecliptic is the path of the stars around Earth, and the Sun’s position on this path determines the length of the yearly cycle. Starting from the vernal equinox, the tropical year has a length of 365 days.
