In which months are the day and the night the same length? Which month has the longest day? Which month has the shortest day? Find the difference hours and minutes between the longest day and night for each date in the table above.

Sunrise: 6:53 am, Sunset: 6:53 pm
Length of day: From 6:53 am to 6:53 pm is exactly 12 hours.
Length of night:

$$24 \text{ hours} - 12 \text{ hours} = 12 \text{ hours}$$

• Length of day: 12 hours 0 minutes
• Length of night: 12 hours 0 minutes

Sunrise: 7:50 am, Sunset: 5:26 pm
Length of day:
From 7:50 am to 12:00 pm = 4 hours 10 minutes
From 12:00 pm to 5:26 pm = 5 hours 26 minutes
Total length of day = (4 hours + 5 hours) + (10 minutes + 26 minutes) = 9 hours 36 minutes.
Length of night:

$$24 \text{ hours} - 9 \text{ hours } 36 \text{ minutes}$$ $$= 23 \text{ hours } 60 \text{ minutes} - 9 \text{ hours } 36 \text{ minutes}$$ $$= (23-9) \text{ hours } (60-36) \text{ minutes}$$ $$= 14 \text{ hours } 24 \text{ minutes}$$

• Length of day: 9 hours 36 minutes
• Length of night: 14 hours 24 minutes

Sunrise: 6:10 am, Sunset: 6:10 pm
Length of day: From 6:10 am to 6:10 pm is exactly 12 hours.
Length of night:

$$24 \text{ hours} - 12 \text{ hours} = 12 \text{ hours}$$

• Length of day: 12 hours 0 minutes
• Length of night: 12 hours 0 minutes

Sunrise: 5:39 am, Sunset: 7:08 pm
Length of day:
From 5:39 am to 12:00 pm = 6 hours 21 minutes
From 12:00 pm to 7:08 pm = 7 hours 8 minutes
Total length of day = (6 hours + 7 hours) + (21 minutes + 8 minutes) = 13 hours 29 minutes.
Length of night:

$$24 \text{ hours} - 13 \text{ hours } 29 \text{ minutes}$$ $$= 23 \text{ hours } 60 \text{ minutes} - 13 \text{ hours } 29 \text{ minutes}$$ $$= (23-13) \text{ hours } (60-29) \text{ minutes}$$ $$= 10 \text{ hours } 31 \text{ minutes}$$

• Length of day: 13 hours 29 minutes
• Length of night: 10 hours 31 minutes

Here is the completed table:

Date	Sunrise	Sunset	Length of day	Length of night
March 23	6:53 am	6:53 pm	12 hours 0 minutes	12 hours 0 minutes
June 21	7:50 am	5:26 pm	9 hours 36 minutes	14 hours 24 minutes
September 22	6:10 am	6:10 pm	12 hours 0 minutes	12 hours 0 minutes
December 22	5:39 am	7:08 pm	13 hours 29 minutes	10 hours 31 minutes
