Two weeks from now will be the first monday after daylight savings time has started. That means the sun will not set until almost 7 PM.
The actual sunset is 6:53 PM for March 8th, but there is still some light out after sunset from sun bouncing off the atmosphere. Civil twilight aka legal darkness is 7:21 PM, which means it won’t be dark until well after 7 PM.
