During April, the days grow significantly longer since the equinox (the first day of spring). The Sun rises earlier and sets later, and is now quite high in the sky at noon. As a result, by month’s end, the length of daylight is almost two hours longer than at the beginning of spring.

Note in the figure that, by the end of April, only a month since the equinox, the Sun is more than halfway to its extreme northern declination. The length of daylight will not change as much during May and June.
