Sabbats
There are eight festivals through the year called Sabbats. The four Greater Sabbats are: Imbolc, Beltane, Lughnnasa, and Samhain. The four Lesser Sabbats are the equinoxes and solstices: Ostara, Litha, Mabon, and Yule. The eight Sabbats represent seasonal birth, death, and rebirth. In them witches honor the Goddess and her cohort, the God.
During the equinoxes the flow of power is stronger; whereas, the solstices are a time for regrouping energy. The celebration of solstices and equinoxes is done on a particular day when the sun changes into particular signs. The Greater Sabbats are celebrated on specific days too. There are two ways to determine the holy days: 1) on a definite day, or 2) on the closest full moon. Since the ancient pagans counted nights instead of days, all their festivals were celebrated on the eve or the night before. The day began at sundown.
As I mentioned before, the Sabbats are time to honor the deities and the change of seasons. It is not necessary to perform magick during them. However, many witches find it fructuous to do so, specially if the time is right for a certain spell or to do divination. Then again, this may vary among traditions.
Esbats
Esbats are nights used by the witch to perform magick. After all we all need a time to raise energy, cast spells, perform healing, etc. You must take into consideration the phases of the moon before performing your works. Esbats are also known as Lunar Rituals. Perhaps the two most well-known Esbats are New Moon and Full Moon celebrations. During Full Moon celebration, the witch performs the Drawing Down the Moon. It is done to empower oneself.
Sabbat: Samhain
It is also known as Ancestor's Night, Feast of the Dead, Shadowfest, Halloween, and All Hallow's Eve. It is celebrated on October 31st. or the first Moon in Scorpio. This is considered the Witches' New Year. The yearwheel has had one full turn. During this night rituals to honor our ancestors are celebrated. It is said that the veil between the worlds is thinner or weaker. Therefore, it is an excellent time for divination. It is a time to shed away all ideas and influences. It is a time of reflection, of looking back over the last year. Black candles are lit to ward off negativity. Orange candles are lit to bring changes. The colors of the season are black and orange.

Sabbat: Yule
This sabbat is also known as Winter Solstice, Winter Rite, Midwinter, and Alban Arthan. Yule is celebrated around December 21st. or the first day of winter. The night prevails over the Earth making it the longest night of the year. In some traditions, it is the time the Holly King overcomes the Oak King. For most pagans this is the time when the Goddess gives to her son, the Sun God. The Winter Solstice has been viewed as a time of divine births. Yule is celebrated by lighting fires or candles, and the use of the Yule log.
It is typical to decorate the Yule tree, make wreaths of holly, and exchange gifts. A portion of the Yule log is saved and kept to protect the house and then to be lighting next year's log. Burn bayberry candles to ensure wealth and happiness throughout the year. These are lit at the beginning of the ceremony. Decorate your altar with mistletoes, holly, colored lights, a candle in the shape of Kriss Kringle (Santa Claus), homemade wreath, and presents wrapped in colorful holiday paper.

This is a Sabbat of purification through the renewing powers of the Sun. This is a good time for self-initiations or initiations into covens. Imbolg involves the vanishing of winter, and it marks the time to welcome Spring. It celebrates the awakening of the land from the long winter. Imbolc is one of the first three Spring festivals. For those who follow the Celtic tradition, it is the festival of the Maiden aspect of the goddess in preparation for growth and renewal. Many wiccan dedicate their rituals to the goddess Brigid, protector of the hearth.

This is the time in which light and darkness, day and night, are in balance. It is not Winter nor Spring. Yet the light is growing stronger. Ostara is second of the three Spring festivals.
Eggs are colored and placed in altars as talismans. This is a good time for a naming ceremony if you are planning to have a witch name. Some witches buy a broom, consecrate it, and name it. The broom will be used to sweep a magickal circle clean. During this time decorate using light green, lemon yellow, and pale pink.

It is known as Mayday or Lady Day. Mayday is celebrated on May 1st., while Beltane on May 5th. or the first Full Moon in Taurus. It is the last of the Spring festivals. This is the time to prepare for the warm months ahead; but also a time of love and union (marriages are common), and the Maypole. Ribbons of bright blue, lavender, warm pink, lemon yellow, and white are used in the Maypole. However, the traditional colors of Beltane are white and red (representing the blood of the woman as her virginity is taken). That is why many traditions honor the Mother aspect of the Goddess on this day. Baskets of flowers are picked at sunrise to decorate the houses and the Maypole. Beltane is a festival with offering to Elementals. It is a time of great magick and divination. It is the perfect time to establish a garden shrine or to honor house guardians. The power of the elves and fairies reach their height on this day.
