Ostara is not only the celebration of the arrival of spring, but also the celebration of the Spring Equinox. On this day, we have the same number of hours of sunlight as we do darkness and day and night are equal. This is the tipping point in the year where the days will now grow longer and longer, until we reach the Summer Solstice. At this time, flowers and trees are blooming and birds are nesting. This is truly a celebration of renewed life all around us. This is a perfect time to cast spells to bring things into our life or create spells of balance.
