Film production in Rennes
Between June and December, usable daylight in Rennes moves by 7h 39min — from 16h 02min down to 8h 23min. 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, the climate profile.
Light and shooting hours
On 15 June, the sun in Rennes rises at 06:07 and sets at 22:09; the evening golden hour starts at 21:20 and runs for 49 minutes. By December that shifts to 08:51–17:14, with a 54-minute golden-hour window from 16:21.
For scheduling, that means the window for the one shot that lives on light runs between 41 and 54 minutes across the year. Put it last in the day and the first overrun takes it.

Blue hour and shooting windows
Blue hour in Rennes starts at 22:34 in June and ends at 22:50 — a window of 17 minutes. In December it is 14 minutes from 17:37. If you need a city view with lit windows, that window is all you get.
Sunset moves fastest around the equinoxes: between March (19:12) and September (20:22) there are 70 minutes of difference. A schedule running over several weeks cannot work from one fixed "sunset" time.
Weather and washout risk
Rennes averages 14 rain days in March and 9 in July. A three-day exterior shoot in March statistically loses 1.4 days — not a forecast, but the basis for deciding whether a cover set belongs in the budget.

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.
