Date Calculator

03 June 2020

Enter a date, convert it, find its day of the week.


In the Date Calculator, you can enter any date and convert it between Gregorian, Julian, Hebrew, and French Republic and find its day of the week. You can enter two dates and find the time span between them. You can do various other date and time calculations and conversions as well.

A unique feature of the Date Calculator versus other date utilities is that you can enter "fuzzy" dates, like just a month and year (APR 1901) or a range of dates (FROM 1845 to 1867), an still do calculations. The calculations will give all possible answers for the date and time information provided. Being able to do calculations with imprecise dates and time spans is a very useful tool for genealogists working with imprecise date information.
