Something all amateur genealogists should consider when making searches in
records dating back into the 18th century:
A shareware program called "Calendar Explorer." Version 1.86
Calendar Explorer is a 32-bit program for Windows 95 and Windows
NT 4.0; it will not work on earlier versions, is a "calendar
utility" with many applications. An application specific to genealogy is
conversions between Gregorian dates and Julian Dates.
A christening date from a church register entry -- 2 Dec. 1735 -- which is
thought to be a Julian date is converted by the program to Dec. 13, 1735 in
today's Gregorian calendar.
The Julian Calendar was introduced by Julius Caesar
in 45 B.C. It served well but had a minor inaccuracy. By the year 1583
the Spring Equinox had drifted by ten days. Pope Gregory XIII ordered
a new calendar which was not widely adopted in western Europe and
North America until the 1700s. Some countries did not adopt it until
the 1800s, and a few, such as Russia, did not change to the Gregorian
Calendar until early this century. Many records of your ancestors show
dates in the Julian Calendar.
Calendar Explorer version 1.86 can also convert between a Gregorian Date and
equivalent Islamic Civil Calendar date and the Indian Civil date.
Another feature is a Week Day finder that finds the week day for a
given date -- for example, when your birthday will happen on a Monday.
Calendar Explorer also can display the American Secular Holidays.
Additionally, Calendar Explorer will calculate the phases of the moon
for any year, dates in the Western Church Year, the date of both
Eastern and Western Easter through the centuries, and the number days
These calculations help genealogists pinpoint Easter's date which helps to
identify the lenten period during which such things as weddings generally did
not take place.
Reference "tombstone dates" -- such as "Died January 3, 1815 at the age
75 years, 5 months and 12 days." The better genealogy programs have
calculators that can figure out birth dates from such information, but
Calendar Explorer cannot.
Calendar Explorer will print calendars in B/W or color. It will also save
graphics files which you can later import into word processors or
Calendar Explorer 1.86 is shareware with a $17 registration fee.
