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.

Decorate your altar with a small Maypole, or a phallus-shaped candle to symbolize fertility, a daisy chain, and springtime flowers. Serve red fruits (like strawberry, cherry, etc.), green herbal salads, red or pink wine, and barley cakes.
