✓
Answer
No it doesn't mean it is in night!
As we know light reaction occurs in light so it means in the presence of sunlight.
It is clear that light reaction is in day time and we know dark reaction doesn't need light rather need its byproducts of light reaction ATP and NADPH as we know photosynthesis occurs In day time so it means both light and dark reaction occurs in day time . By name dark it doesn't means it is occurs in night but also it is misnomer term that dark reaction doesn't need light rather by products formed in light reaction to convert $\mathrm{CO}_2$ into sugar.
