Between June and December, usable daylight in San Juan moves by 2h 12min — from 13h 14min down to 11h 02min. An exterior day in December is a different day from one in June. This page carries sunrise, sunset and golden-hour times for all twelve months.
Light and shooting hours
On 15 June, the sun in San Juan rises at 05:49 and sets at 19:03; the evening golden hour starts at 18:31 and runs for 31 minutes. By December that shifts to 06:50–17:51, with a 32-minute golden-hour window from 17:19.

Blue hour and shooting windows
Blue hour in San Juan starts at 19:18 in June and ends at 19:27 — a window of 9 minutes. In December it is 9 minutes from 18:06. If you need a city view with lit windows, that window is all you get.
Sunset moves fastest around the equinoxes: between March (18:35) and September (18:28) there are 7 minutes of difference. A schedule running over several weeks cannot work from one fixed "sunset" time.
Planning a shoot here
A schedule that ignores these numbers looks fine on paper and falls over on the day. TillyGen folds sun position, travel and crew availability straight into the schedule — if the exterior no longer fits before sunset in December, the plan says so, not the wrap report.
