How to use the almanac: Select a location close to where you live
from the pull-down menu. The almanac opens with the Universal Time
(UT) and calendar date based on your computer's clock. The
corresponding local date and time, day of the week, latitude, longitude and time
zone are also displayed. You may enter any new date and UT between
Jan. 1, 1600, and Dec. 31, 2400, then click 'Calc' to update the almanac.
Clicking 'Reset' restores the almanac to the current date and time. You
may also step forward or backward in time by one hour, day, or week by
clicking the appropriate button above.
