Tolkien too

" ….the medieval church considered 25 March to be the single most important date in history: it was both the beginning and the end of Christ’s life on earth, the date of his conception at the Annunciation and his death on Good Friday. To underline the harmony and purpose which, in the eyes of medieval Christians, shaped the divinely-written narrative of the history of the world, 25 March was also said to be the date of other significant events: the eighth day of Creation, the crossing of the Red Sea, the sacrifice of Isaac, and other days linked with or prefiguring the story of the world’s fall and redemption. The date occurs at a conjunction of solar, lunar, and natural cycles: all these events were understood to have happened in the spring, when life returns to the earth, and at the vernal equinox, once the days begin to grow longer than the nights and light triumphs over the power of darkness. The resonances of 25 March reached even unto Middle Earth, as Tolkien aligned the downfall of the Ring to this most auspicious of dates."
