Alaska does have extended periods of darkness during winter, but the famous "30 days of night" refers to Barrow, the northernmost city, where the sun sets on November 18 and doesn't rise again until January 22, resulting in about 65 days of darkness. Other parts of Alaska may experience varying degrees of darkness during winter, with some areas not experiencing total darkness for 67 days.
The places closest to the poles, such as the Arctic Circle, experience the longest days. In the Arctic, particularly locations like northern Norway, Alaska, Iceland, and Canada, the summer solstice can have over 24 hours of daylight, with the sun not setting for several days in a row due to the Earth's axial tilt.
In Alaska, the longest day occurs on or around June 21st, known as the summer solstice, when the sun is up for about 22 hours. Conversely, the longest night happens on or around December 21st, known as the winter solstice, when the sun may be up for only a few hours in some parts of Alaska.

Seven days strength of any concrete usually comes 67% of 28 day strength. So 7 day strength of M30 may be .67*30=20.10 MPa
Adding 67 days to October 24 in any year gives December 30 of the same year.
Seven days strength of any concrete usually comes 67% of 28 day strength. So 7 day strength of M30 may be .67*30=20.10 MPa
67 x 30 = 2010
30% of 67% is 20.1%.
Including the start and end dates in the calculation, there are 67 days between the two dates.
67 days is 9 weeks and 4 days
