Special Birth Date Entry

Chart of the Moment
If you wish a chart of the moment, please, leave the first name field empty and type "now" into the last name field. After selecting a unique place and pressing the "continue" button, the date and time of the moment will be filled into the form.

Years before 100 A.D.
When entering a year, you can usually omit the two first digits of the year number. E.g., a year value "79" will be interpreted as "1979". If the year 79 A.D. is required, you will have to enter "079". For the year 5 A.D. please enter "005".

The program usually assumes Gregorian calendar dates. If a Julian calendar date is required, please, enter "jul" after the year number, e.g. "1066 jul". For most historical data before the year 1582 you will want to enter "jul".

We have decided not to take care of the calendar switch by an automatic feature. Many history books have converted historical dates to the Gregorian system, while other sources have kept the dates in the original Julian system. There is no way for our computer to know what your source of the birth data did in regard to this calendar conversion.

Years B.C. have to be entered as negative numbers. Attention, the astronomical year counting is to be used. The historical year 3 B.C. is -2 in the astronomical counting style. The difference arises from the fact that the historical counting style has no year zero, while the astronomical style allows for the year zero.
