• For iteration of date ranges, frequency of year/day/hour/minute
• For iteration of date ranges, stride as interval of frequency

World transit queries

All planetary alignments on date

• Receives alignment and orb conditions as angles
• Returns dictionary of all planetary separations (triangular matrix)

Planetary alignment in range of dates

• Receives two planets and alignment and orb conditions as angles
• Returns generator of time series of planetary separations, and whether they are within orb

All planetary alignments in range of dates

• Receives alignment and orb conditions as angles
• Returns generator of time series of dictionaries of planetary separations (triangular matrices)

Natal transit queries

All planetary to natal alignments on date

• Receives birth date, and alignment and orb conditions as angles
• Returns dictionary of all planetary separations from their natal configuration (square matrix)

Planetary to natal alignment in range of dates

• Receives one planet and one natal planet, birth date, and alignment and orb conditions as angles

Query combinations

Using the ResultSet class, the above may be combined under arbitrary Boolean operations. For example:

• Hard alignment: Planet 1 conjunction OR opposition OR square Planet 2
• Soft alignment: Planet 1 trine OR sextile Planet 2
• T-square: Planet 1 opposition Planet 2 AND Planet 3 square Planet 1
• Grand trine: Planet 1 trine Planet 2 AND Planet 2 trine Planet 3 AND Planet 3 trine Planet 1
• Grand cross: Planet 1 square Planet 2 AND Planet 2 square Planet 3 AND Planet 3 square Planet 4 AND Planet 4 square Planet 1
