I'm not sure that I can think of an equivalent example in any of the plays to the importance of dawn, as in the time of day, to Romeo and Juliet. Several commentators have pointed out the way the different sections of the play either begin or end with it. The play itself doesn't begin at dawn, but Benvolio's description to Lady Montague of having seen Romeo "underneath the grove of sycamore" refers to it. The second dawn arises at the end of the balcony scene in Juliet's orchard, and the third comes as Romeo leaves Juliet's window after their wedding night (and after their unforgettable discussion of whether it's the lark or the nightingale that they're hearing). The fourth arrives as the Nurse arrives to find Juliet seemingly dead, but only counterfeiting it with the assistance of Friar Laurence's potion. And the final one comes with the Prince and the remaining family members finding the dead bodies in the tomb. Clearly Shakespeare intended it to be part of the fabric of the play, and of course it can be taken symbolically in several ways. One would be as a representative of a fresh start (a "new day", as the saying goes) or a chance to turn the page, which nearly happens several times in the play but never does completely. And of course, the other would be that dawn is to a day what youth is to a life, which leads us to still more thematic considerations regarding time. More on these tomorrow.
