Needed Message-ID: <5045@uwmcsd1.UUCP> Date: 3 Mar 88 21:14:19 GMT Sender: daemon@uwmcsd1.UUCP Reply-To: burkett@csd4.milw.wisc.edu (Edward W Burkett) Organization: Dept. of Biological Sciences -- Univ. of Wisconsin - Milwaukee Lines: 17 I am conducting research in which I need to know the length of day for every day in 1984-1986. I recently saw a program posted which gave the time of sunrise and sunset for the current day but with my limited programming skills could not modify it to give the dates I required. I need this information specifically for longitude 88.01.00 latitude 40.23.00 and would like to be able to select the dates of interest. I am working on a Unisys 7000/40 using the Unix 4.3bsd+ operating system. We have Berkley Pascal and C for this operating system. If anyone knows of a program that does this or can modify an existing program I would greatly appreciate the help. Please respond with email if possible. Edward W Burkett burkett@csd4.milw.wisc.edu
