the winter solstice was on 21st december and since then the days get longer at both ends equally until 21 March at which point day = night lengthwise as its the equinox Latin equal night, the days continue to lengthen until approx 21 June which although called midsummer night, is actually the Firstday of summer and not midsummer at all so there's a good question. oh, also the clocks go backwards and forwards in autumn and spring due to govt interference and sympathy for farmers but not for children in the dark at 4:30
Apart from that, sometimes the moon rises in the day and sets at night and the stars, where do they go in the day? - Nowhere; they're just blinded by the sunlight. :-)
