Location Adjustments

OUTSIDE THE U.S.: Although north-south boundaries of the software are from 50 to 20 degrees N. Latitude, and east-west boundaries are from 60 to 160 degrees W. Longitude, the Ultimate PrimeTimes app can be adjusted to be reasonably accurate for virtually any Longitude or Latitude in the Northern Hemisphere and slightly less so for the Southern Hemisphere. Please consider the following explanations for your hemisphere:

Northern Hemisphere
The Best Periods feature of the app is determined by the moon's zenith (when at its highest point in the sky each day) and its sub-zenith (when underfoot on the other side of the earth). Neither of these zeniths is affected by latitude, so the app is accurate for the beginning and ending times of both lunar periods, as well as for their placement within the Top Periods list. The same is true for exact times of Dawn, Noon, and Dusk, all thanks to GPS. And while each day's Daily Rating value could be lowered with each degree of latitude you are above 50 (due to the decreasing angle of the sun and moon), the all-important relativity of one day to the next remains the same.

The bottom line is that the app offers you reasonably accurate predictions of the best days and best times of day to go, even as far north as Alaska.

Southern Hemisphere
Down here, you need to consider a couple other things. First, your summer (which is the sun's highest point in its "High-Low" cycle) is Ultimate PrimeTimes' winter (Low Sun). And vice versa. Along the same line, PrimeTimes' "High Moon" is your "Low Moon," and vice versa. This would alter any given day's value in the Daily Rating, but not so much its relativity to the day before and after. And this relativity is what really matters. You want to be fishing/hunting on those days that are stronger than the adjacent days, or those weeks that are stronger than the adjacent weeks.

As for the solar periods, Noon and Midnight's peaks (centers) would be the same, but their and all solar periods' length would be just the opposite during summer and winter (ie: on the first day of winter one is about 1.5 hours long in Primetimes, while on the first day of summer it's 3.2 hours long. These would be just the opposite for you.) However, on the first days of spring and fall (when the solar periods are closer to 2 hours), they would be about the same length. The times of Dawn, Noon and Dusk, plus their placement in the Top Periods list on the program would be off, again because your summer is the program's winter and vice versa.

Basically, the same would be true for the lunar periods, but on a monthly basis, rather than a seasonal one. Each peak would be the same, but the length would be just the opposite (ie: if the period were 3 hours long in PrimeTimes, it would really be only one hour for you...and vice versa). On the other hand, 2-hour-long periods would be the same for you.

So, while both the moon and the sun's High-Low cycles are exactly opposite in the southern hemisphere, all the other cycles figured into PrimeTimes are exactly the same. These cycles, which account for approximately 75% of the PrimeTimes data, include:

1) the moon's phase;
2) the moon's apogee-perigee cycle (how close the moon is to the earth);
3) when the moon and sun reach their highest and lowest points in the sky during each 24-hour period;
4) and those all-important solar-lunar overlaps.
