This pagan holiday is often celebrated around February 2nd. It kind of corresponds with Groundhog's Day and Candlemas. This holiday is halfway between the winter solstice and the spring equinox.
People often celebrate the fact that the days are beginning to get noticeably longer and in some areas, the weather is warming too. In Colorado here, we can usually expect winter weather until May, though this year may be different. We've had very little snow and there are days above 40 degrees often, which is very unusual.
As the sun returns and the days become warmer, many people celebrate the potential and hope for the coming year. Many think about the seeds that will be planted, literally and figuratively. At the Imbolc ritual I'm hosting, the plan is to discuss the various things we are all manifesting for the year.
Much like mother nature beginning to awaken, we too can awaken things in ourselves. That might be starting a new fitness plan, or it might be something more emotionally oriented.
For more celtic traditions, Brigid or St. Brigid, is the goddess called upon to work her magic in our lives. She had her hand in many things, including healing, smithing, and creative pursuits. She is the perfect goddess for this time. Weaving a Brigid's cross is often done during Imbolc, with the cross placed above the front door or in the kitchen to bring prosperity. With the new cross created, the old one is burned, a symbol of letting go of things unwanted and unneeded from the previous year.
What are you looking to manifest this year?
