To OP,

Apart form Epoch,

as far as I know the calander used in 1609 in Ireland/Uk was the old Julian calandar, while Europe used had changed by that time to current Gregorian calandar. Think there was about 10 days difference in it at that time. AT a later stage UK/Ireland changed their calandar to match rest of Europe. You would need to know if the date quoted in 1609 was old vs new calandar as software today will run off new dates..

There may be a convention on how historians report dates between the time of adoption of calendars in UK and mainland Europe. Someone may be able to answer this ?

the gregorian calender was adopted on oct 4th 1582 in catholic countries in which 10 days were dropped from the calender so october only had 21 days, some countries took it up immediately some took months or years to change. england did not adopt the calender for another 170 years.
