I still think it is "one". because there are not an integer number of days per year so you don't get and exact repeat in 6 months. Maybe a pin hole would only work once ever? I don't know. To "work" the pinhole has to exactly line up with the detector at the exact same time of day. But I'm not liking slits either because I can't see how to adjust them to exact vertical. I'm back to the first thing I thought of, a wire with a large weight. Then you measure the light curve as shadow of the wire sweeps over the detector.
