G\u00fcn\u00fcm\u00fcze kadar ula\u015fabilen en eski g\u00fcne\u015f saati ise, M\u0131s\u0131rl\u0131lara ait olup, M.\u00d6. 800 y\u0131llar\u0131ndan kalmad\u0131r. Bu uzun bir ta\u015f s\u00fctunun \u00e7evresindeki alt\u0131 i\u015faretten olu\u015fuyordu. Sabahleyin do\u011fuya, ak\u015fam olunca da bat\u0131ya \u00e7evrilen ta\u015f\u0131n i\u015faretli ucunun d\u00fc\u015f\u00fcrd\u00fc\u011f\u00fc g\u00f6lgelerin yard\u0131m\u0131yla, zaman belirleniyor.<\/p>\n

Eski Yunanda de\u011fi\u015fik g\u00fcne\u015f saatleri kullan\u0131lm\u0131\u015ft\u0131r. Pergal\u0131 Apollonius (M.\u00d6. 250) konik kesit kullanarak daha da hassas saat <\/a>elde etmi\u015ftir. Ptolemi ise kurdu\u011fu d\u00fczende g\u00f6lgeleri \u00e7e\u015fitli e\u011fik d\u00fczlemlerde g\u00f6sterir saat geli\u015ftirmi\u015ftir. Atina\u2019daki bir kulede M.\u00d6. 100 y\u0131l\u0131ndan kalma sekiz g\u00fcne\u015f saati bulunmaktad\u0131r.

Babilliler, Yunanl\u0131lar ve Araplar taraf\u0131ndan de\u011fi\u015fik bi\u00e7imlerde yap\u0131lan g\u00fcne\u015f saatleri, 14. y\u00fczy\u0131ldan itibaren Avrupa’da kiliselerin ve b\u00fcy\u00fck binalar\u0131n \u00fczerlerinde de g\u00f6r\u00fclmeye ba\u015fland\u0131.

R\u00f6nesansla g\u00fcne\u015f saati yayg\u0131nla\u015ft\u0131. Ancak 19. y\u00fczy\u0131ldan \u00eetib\u00e2ren s\u00fcs olmaktan ileri gitmemi\u015ftir. G\u00fcne\u015f saatinin \u00e7al\u0131\u015fma prensibi, g\u00fcne\u015fin g\u00f6kteki hareketi ile ilgilidir.
