Ciao Mark I am pretty somewhere you find converters for Julian <=> Gregorian conversion. But ... complexities arise for historians that ... 1 - ... different societies transferred from one to the other at different dates. And the later the transfer date the greater the number of days that get destroyed. So solutions would need to account for country variations. That could get a little complicated ... 2 - ... a difficult problems in history is if, say, you wanted to find a day in England and then find the French equivalent where France converted and Britain hadn't. However ... 3 - When quoting dates from historical documents (for a single country) it is not often necessary to calculate the date as the document itself bears the socially recognised date. 4 - Also, in many cases, during the transition period between calendar systems, both the old and new dates were recorded.
