Thus genealogists have to deal with a long period of ambigous record dates for English and colonial records from 1 January through 24 March, in years prior to 1753.

By the ninth century, parts of southern Europe began observing first day of the new year on March 25 to coincide with Annunciation Day (the church holiday nine months prior to Christmas celebrating the Angel Gabriel's revelation to the Virgin Mary that she was to be the mother of the Messiah).

C., Julius Caesar ordered a calendar consisting of twelve months based on a solar year.

This calendar employed a cycle of three years of 365 days, followed by a year of 366 days (leap year).The changes implemented that year have created challenges for historians and genealogists working with early colonial records, since it is sometimes hard to determine whether information was entered according to the then-current English calendar or the "New Style" calendar we use today.
