Since summer (and other seasons) can begin and end on different days each year on the astronomical calendar, it can be hard to compare seasons from year to year in this way. To standardize the length and start of the seasons, in meteorology, the 12 months of the year have been split up into four, 3-month periods. Therefore, in the meteorological calendar, summer includes the months of June, July and August - always starting on 1 June and ending on 31 August.
NADPH or NADP plus stands for Nicotinamide Adenine Dinucleotide Phosphate. NADPH is created in the Stoma on the duration of light reactions accumulation.

Thus, light energy is initially converted to chemical energy in the form of two compounds: NADPH, a source of energized electrons (reducing power); and ATP, the versatile energy currency o that the light reactions produce no sugar; that happens in the second stage of photosynthesis, the Calvin cycle.he light reactions are the steps of photosynthesis that convert solar energy to chemical energy. Light absorbed by chlorophyll drives a transfer of electrons and hydrogen from water to an acceptor called NADP+ (nicotin-amide adenine dinucleotide phosphate), which temporarily stores the energized electrons.
