By default, all dates entered in GenoPro are assumed to use the Gregorian Calendar, however we have an interface to convert those dates to other calendars. Microsoft standard did a great job for date & time globalization. The Julian Calendar class recognizes only the current era. Unlike the Gregorian calendar, the Julian calendar defines a leap year as a year that is evenly divisible by four with no exceptions; therefore, the calendar is inaccurate by one day every 128 years. A common year has 365 days and a leap year has 366 days. The date January 1, 2001 A.D. in the Gregorian calendar is equivalent to the 19th day of December in the year 2000 A.D. in the Julian calendar. The Hebrew Calendar recognizes two eras: B.C.E. (before the common era) and A.M. (Latin "Anno Mundi", which means "the year of the world"). This implementation of the HebrewCalendar class recognizes only the current era (A.M.) and the Hebrew years 5343 to 5999 (1583 to 2239 in the Gregorian calendar). In every 19-year cycle that ends with a year that is evenly divisible by 19, the 3rd, 6th, 8th, 11th, 14th, 17th, and 19th years are leap years. A common year can have from 353 to 355 days, depending on the placement of Jewish holidays. A leap year can have from 383 to 385 days. The Hijri Calendar recognizes one era: A.H. (Latin "Anno Hegirae", which means "the year of the migration," in reference to the migration of Muhammad from Mecca). In every 30-year cycle that ends with a year that is evenly divisible by 30, the 2nd, 5th, 7th, 10th, 13th, 16th, 18th, 21st, 24th, 26th, and 29th years are leap years. A common year has 354 days and a leap year has 355 days. The Japanese Calendar recognizes one era for every emperor's reign. The current era is the Heisei era, which began in the Gregorian calendar year 1989. The era name is typically displayed before the year. For example, the Gregorian calendar year 2001 is the Japanese calendar year Heisei 13. Note that the first year of an era is called "Gannen"; therefore, the Gregorian calendar year 1989 was the Japanese calendar year Heisei Gannen. The date January 1, 2001 A.D. in the Gregorian calendar is equivalent to the first day of Ichigatsu in the year Heisei 13 in the Japanese calendar. The Korean Calendar works exactly like the Gregorian calendar, except that the year and era are different. The date January 1, 2001 A.D. in the Gregorian calendar is equivalent to the first day of January in the year 4334 of the current era in the Korean calendar. The Taiwan Calendar works exactly like the Gregorian calendar, except that the year and era are different. The TaiwanCalendar class recognizes only the current era. The date January 1, 2001 C.E. in the Gregorian calendar is equivalent to the first day of January in the year 90 of the current era in the Taiwan calendar. The ThaiBuddhistCalendar works exactly like the Gregorian calendar, except that the year and era are different. The date January 1, 2001 A.D. in the Gregorian calendar is equivalent to the first day of January in the year 2544 of the current era in the Thai Buddhist calendar.

I understand that the internal storage is in one format. The problem is that over the years the format has changed.
If you look on the IGI (International Genealogical Index) for John Steere born in 1660 in Sussex there are two dates:-
Birth: 01 MAR 1659
Christening: 11 APR 1660 Rogate, Sussex, England
It appears that the Christening (Baptism) took place 13 months after birth but in fact they were only a month apart.
The conventional genealogical way to express the first date is 1 March 1659/60. Several, but not all, genealogical programs allow the entry of such a date format.
I suspect that other users will have similar but different problems.

The design for the new date format is very flexible and robust. I have a solution in mind for the problem you are describing. Just wait until this feature is out. I won't release GenoPro 2.0 until those problems have been solved. GenoPro is a true multilingual software, and it goes along to support multiple date calendars.

Concerning Julian-Gregorian change: not all the countries change at the same time. For example, until the october revolution (1905) Russia did not change (this is why the celebration of the october revolution is 7th of November  )

Concerning Julian-Gregorian change: not all the countries change at the same time. For example, until the october revolution (1905) Russia did not change (this is why the celebration of the october revolution is 7th of November ) You are right, this is a real issue. As a solution, GenoPro uses a proleptic calendar for all dates. It is the responsibility of the user to pick the right calendar before inputting a date from the chosen calendar. If you wish to enter Julian dates, then pick the Julian Calendar. GenoPro will use that calendar until you pick another calendar. 
For instance, the date December 31, 0099 in the Gregorian calendar is January 2, 0100 in the Julian calendar. In real life, the Gregorian calendar is used for dates on or after October 15, 1582, however you may express any date using the Gregorian calendar - although the Gregorian calendar may not have been the official calendar at that specific date.

The new date support is cool!!I did found a problem, though. The conversion to the Hebrew calander is not working for me. For example - I have someone who died on 30 Nov 1984. Converting to the Hebrew calander with Hebrew (English) is working great. It is converted to 7 Kislev 5745, which is wrong. It suppose to be 6 Kislev 5745. This is the first problem. When I select Hebrew as language what I get is: 7 ספטמבר 5745. The month written in Hebrew is September!! which is not either the original month (November) nor the Hebrew one (Kislev)!

It is possible the conversion of months is wrong. In fact, I just noticed I forgot the 13th month in the Hebrew calendar  . This is really embarassing. Can someone tell me what is the proper date (in the Hebrew calendar) and I will adjust/rotate the months so they appear correct. This is the output from GenoPro: Output from GenoPro
Today 's date in the Gregorian calendar: Tuesday, June 06, 2006
Today 's date in the Hebrew calendar: יום רביעי, מרץ 11, 5766
Months in the Hebrew calendar:
Month #1 (Jan): ינואר
Month #2 (Feb): פברואר
Month #3 (Mar): מרץ
Month #4 (Apr): אפריל
Month #5 (May): מאי
Month #6 (Jun): יוני
Month #7 (Jul): יולי
Month #8 (Aug): אוגוסט
Month #9 (Sep): ספטמבר
Month #10 (Oct): אוקטובר
Month #11 (Nov): נובמבר
Month #12 (Dec): דצמבר
Month #13 (Sol): Yehudad (6/6/2006)
I have someone who died on 30 Nov 1984. Converting to the Hebrew calander with Hebrew (English) is working great. It is converted to 7 Kislev 5745, which is wrong. It suppose to be 6 Kislev 5745. The date conversion from Gregorian calendar to Hebrew is not always accurate. Depending on the time of the day, the same date may be span two days in the Hebrew calendar. In the Hebrew calendar, the day starts at sunset (Genesis, Ch.1 v.5); but for lunar-based calendar calculation, the zero-hour used is at 1800h (6 p.m.) civil time, or Jerusalem meridian 2 hours 21 minutes East of Greenwich time. As a result, someone who died after 6 p.m. will not be on the same day on the Gregorian calendar than someone who died in the morning.

This is the output from GenoPro: Output from GenoPro
Today 's date in the Gregorian calendar: Tuesday, June 06, 2006 Today 's date in the Hebrew calendar: יום רביעי, מרץ 11, 5766 This is the first mistake. The month is wrong. Today's date in the Hebrew calander is 11 Sivan 5766. What you quoted is right in day and year. The Month which is written is March in Hebrew!! it should be סיון, which is how Sivan written in Hebrew.

Month #3 (Mar): מרץ
Month #4 (Apr): אפריל
Month #5 (May): מאי
Month #6 (Jun): יוני

Month #8 (Aug): אוגוסט
Month #9 (Sep): ספטמבר
Month #10 (Oct): אוקטובר
Month #11 (Nov): נובמבר
Month #12 (Dec): דצמבר
Month #13 (Sol): This is the second mistake. You have the Gregorian months with their translation to Hebrew. The correct one should be: Month #1 (Tishrei): תשרי
Month #2 (Cheshvan): חשוון
Month #3 (Kislev): כסלו
Month #4 (Tevet): טבת
Month #5 (Shevat): שבט
Month #6 (Adar): אדר
Month #7 (Nisan): ניסן
Month #8 (Iyar): אייר
Month #9 (Sivan): סיוון
Month #10 (Tammuz): תמוז
Month #11 (Av): אב
Month #12 (Elul): אלול
As you saw the Hebrew calander is very problematic. Rosh Hashana which is the holiday of the start of the year is in Tishrei (Month #1), but it is actually Month #7 according to the Bible. The first month is Nisan (Month #7). From what I see, I can only guess that the translation you used is using the Bible method. By that today's month is Sivan which is the 3rd from Nisan, by using the Gregorian calander and it's 3rd month you got March!! Therefore, I think that the correct order should be: Month #1 (Nisan): ניסן
Month #2 (Iyar): אייר
Month #3 (Sivan): סיוון
Month #4 (Tammuz): תמוז
Month #5 (Av): אב
Month #6 (Elul): אלול
Month #7 (Tishrei): תשרי
Month #8 (Cheshvan): חשוון
Month #9 (Kislev): כסלו
Month #10 (Tevet): טבת
Month #11 (Shevat): שבט
Month #12 (Adar): אדר
Month #13 (Adar II): אדר ב in case of a 13 months year Month #12 becomes Adar I - אדר א. Hope that this is not too confusing...

As a result, someone who died after 6 p.m. will not be on the same day on the Gregorian calendar than someone who died in the morning.I'm well aware of that calculation. Can you add a checkbox for after sunset indication? If this checkbox is checked then you take the following Hebrew date. Thus, 6 Jun 2006 without the checkbox checked will be 11 Sivan 5766 and with the checkbox checked it will be 12 Sivan 5766?
