Decimal/Days Equivalents [Astro*Index]

The following table gives the equivalents in days for decimal portions of a degree. Useful in solar arc and progression work. To use the table, you have to find the whole degree portion of the diurnal solar motion in seconds divided by 3600 to equal the percentage of one degree. The distance between two planets can then be multiplied by the percentage. Percentages of a year are given in increments of .05% of a day 1 minute of solar arc is equal to approximately 6 days.
