Can you predict when Manhattanhenge will occur this year?

Manhattanhenge
Weather permitting and proper location, you might be able to celebrate the alignment of the Cosmos, as the New York City's founders planned in all their ancient wisdom!

The Manhattanhenge events are two summer sunsets and two winter sunrises.
I can look up Manhatten's latitude,
latitude = 41.2° N
and equate the amplitude to the known tilt of the street grid from the cardinal directions,
amplitude = 29°
and using
sin ( DECLINATION ) = cos ( LATITIDE ) sin ( AMPLITUDE ), to find the Sun's declination,
alignment declination = 21.3939° north or south
Compare this to an almanac or an analemma ( find one on image search ) and then predict the 4 dates.
