Best times to visit the Matsubayashi-Gallivan Center Sundial

The best times to visit the dial are at the solstices and equinoxes as part of an informal celebration of the change of the seasons. Technically, the solstices and equinoxes occur when the Sun reaches particular positions in the celestial sky along the ecliptic. These astrometric solstices and equinoxes do not occur when the Sun is transiting Utah. On the day of solstice or equinox, local communities usually celebrate their local solstice of equinox. The local Utah solstice or equinox occurs on the day of the astronomical equinox when the Sun transits - or reaches the noon mark on the Asteroid Landed Softly sundial.

Schematic of dial posts on inner and outer ring

Converting dial time by the inner and outer rings of posts to watch (standard) time

Click on the chart to the left to see a schematic numbering each of the posts and corresponding hour lines on the Gallivan Center Sundial. Enter the table below by the day-of-year in the left-hand column. Read to the right to column with the applicable post number. The standard time that the light gnomon will cross that post number is shown in the cell. Information about the equivalent standard time length of a seasonal dial hour, 1/2 hour, 20 minutes and 15 minutes for that date are shown in the far right-hand columns.

To arrive at the dial at the time indicated in these tables, your watch must be set to an accurate time. Use the the United States Naval Observatory's "Master Clock Time" web application to check the time shown on your watch.

Note on Daylight Savings Time (DST) and Handy Table No. 5: The Daylight Savings Times listed in Table No. 5 are based on the United States DST statute in effect in the summer of 2006. Under that law, DST begins on the last Sunday in March and ends on the last Sunday in October. Beginning in 2007 as a two-year temporary experiment, DST will begin on the second Sunday in March and end on the first Sunday in November. Then Congress will decide if the DST change will be made permanent. After March 2007 and during the DST expansion experiment, some of the Mountain Standard Times (MST) and Mountain Daylight Times (MDT) will need to be adjusted manually during the one week expansion periods. Table No. 5 is useful through 2015. Is is prepared on the assumption that the DST experiment will not be permanently adopted by the U.S. Congress.

You are the gnomon

The following table is used to determine local apparent time using your own shadow as the gnomon. The point where one's shadow ends is noted on the ground. The length of your shadow is then paced off using your feet. After counting the number of your feet lengths that equals the shadow length, the corresponding local apparent time is read from the table. An educated person between 700 C.E. through 1850 C.E. used such a table to quickly estimate the time of day. The following table only provides good estimates for persons near 41° North latitude. The height or age of the person is not relevant. The major parts of the anatomy of a child and an adult, such as ratio of the size of their feet to their height, does not change appreciably with age.

Parapegma

A parapegma is a table of rising constellations after sunset. In Greek and Roman times, persons would memorize their parapegma as common knowledge - much like we would memorize multiplication tables today. Using the table of rising constellations at sunset and knowing the number of seasonal hours at night for given month, it is possible to tell time at night. For example, in June Sagittarius is the rising zodiac constellation at astronomical twilight. There are 45 minutes or 3/4 of a standard hour to a seasonal hour. In 6 seasonal hours - or (6 * .75) 4 1/2 standard hours, Sagittarius will transit. That will occur at approximately 2:30 am in the morning.

The columns labelled "Zenith Constellation", "Transiting Equator", and "Transiting Zodiac" are useful for observation planning. Those are the constellations that will be most favorably positioned for viewing. Use this table to enter your guidebooks that are organized by constellation name. It is useful to look at the following month in the table when planning a night. Two hours after astronomical twilight, transiting constellations will be the ones listed in the following month.

In modern amateur practice, an analogous table is Table 1 - Approximate Sidereal Time in Volume One of Burnham's Celestial Handbook (p. 59). Such planning is normally done with a planisphere - an inexpensive disk that can be purchased at your local planetarium.
