Calendar

 

Since we are using dates for some data in this web, we should be careful about the existance of two calendars.

 

The Julian Calendar or Old Style calendar & the Gregorian Calendar or New Style .

 

We are covering data from 1650 until 1850, approximately, from many nations. During this period, some nations still were using the Old Style calendar.

 

These are the nations we should be careful of and the date they changed to the Gregorian Calendar, in addition care must be taken where a date falls between January 1st and March as many Countries year started on March 25th (including England) or March 1st.

Spain15821556
France15821564
