Dagaz is the letter D
Anglo-Saxon Rune Poem (from ragweedforge.com)
Day, the glorious light of the Creator, is sent by the Lord;
it is beloved of men, a source of hope and happiness to rich and poor,and of service to all.
Dagaz, (Day) is the rune of day, dawn, transformation, change, and time. It is time as immediate and quicky, the moment to moment, and day to day. As the rune that follows Inguz, (which is the rune of the week) Today (Sunday) seemed to be filled with great energy and action, and with the need for constant motion to keep resolving things, as things change, shift, transform, and move ever forward.
For me personally, I made my ritualized observance of the change of the season on the Wiccan liturgical calendar. Some call it Ostara, I just prefer the Spring Equinox. While the equinox is more a time of Inguz, it is also a time of Dagaz, as the catalyst sets the change of Dagaz in action. In virtually every climate, life will be springing forth in the northern hemisphere, somehow. In colder places, the snow will probably start a great retreat and flowers and leaf buds will begin to appear. In warmer climates, like Southern California, It is probably the greenest season of all, as the possible for rain still exists, but other weather patterns which are usually cooler and overcast, allow plant life to flourish before the burning heat of summer sets in and strips the hills and exposed areas of smaller plant life. Changes are turning, and now having aligned myself with the change, I can see the transformation come through and participate more closely with it.
