← March This month May → DXpeditions

46 contests running this month. Names only at this zoom — tap a contest for its times, in your own clock or UTC. A contest running across midnight appears on every day it is on the air, with marking the days it continues into rather than starts. Days are UTC, so a contest opening 2200Z sits on the UTC date — which may be the evening before where you are.
