It really depends on what you want the final result to look like. You could take one frame per hour for an entire year and at 24 fps you would end up with six minutes of footage. But that footage would include alternating night and day about every half second. For six long minutes. Lights on. Lights off. Lights on. lights off. You get the picture.
Since you are going to wind up with about one second of footage per day, I would try to take all the frames for each day in a very short period and begin the next day's frames at the same time the previous day's frames ended. You could start on Day 1 at just before sunrise and program it to take 20 frames at a six second interval over 2 minutes. The next day take the 20 frames beginning six seconds after the previous frames ended. At the end of the year your last frames would be taken a tad over 12 hours later in the day than your frames on day one were. Each minute of footage will reflect two hours of your year long day. Your shooting schedule would look something like this:
Day 1 - 20 frames at 6 second intervals beginning at 5:50 a.m.
Day 2 - 20 frames at 6 second intervals beginning at 5:52 a.m.
Day 3 - 20 frames at 6 second intervals beginning at 5:54 a.m.
And so on for the entire year. Day 6 would begin at 6 a.m. Day 36 would begin at 7 a.m. Day 186 would begin at noon. Day 365 would end 6 seconds before 6 p.m.
If you begin Day 1 on the date of the Winter solstice (December 21 for the Northern Hemisphere and June 21 for the Southern Hemisphere), sunrise will get progressively earlier each day along with your frames being progressively later during the times they are shot in the morning, so you would have a smooth progression of any shadows cast by the sun in your yard . By the time of the Summer solstice you would be shooting right around noon, and at the end of your year you would be shooting slightly later each evening as the sunset occurs slightly earlier in the evening.
