Is the statement Days are longer during an equinox true?

No, the statement "Days are longer during an equinox" is not true. During an equinox, day and night are approximately equal in length, with each lasting about 12 hours. This occurs twice a year, around March 21 (vernal equinox) and September 23 (autumnal equinox). Days become longer than nights after the vernal equinox and shorter than nights after the autumnal equinox.
