Years of experience and plantings have taught me to plant seeds and seedlings by soil temperature, not by the calendar. Planting while the ground is still too cold causes the seed to sit dormant until it warms up enough to germinate or kills it. Soil temperature is clearly dependent on the lengthening daylight as the sun warms the soil top down. But the length and severity of winter can keep the ground cold longer as it thaws from the bottom up. The best gauge of when to plant is soil temperature.
So hang in there just a little bit longer.
P.S. Although the soil is still too cold for planting, it’s prime time to be soil blocking or creating plug trays indoors.
