Tuesday, June 21 - the summer solstice or first day of the Northern hemisphere summer - is the longest day of the year, reckoned by the length of time the sun is above the horizon.
In Grand Haven on the summer solstice, the sun will rise at 6:06 a.m. and set at 9:28 p.m., giving us 15 hours and 22 minutes of face time with the sun.
If twilight is included, the period of time before and after sunrise and set when there is still enough diffuse sunlight to see easily, we have a little more than 16 and a half hours of play time.
