What are days for?
Days are where we live.
Parish records record the date of baptism rather than the date of birth and the date of burial rather than the date of death, although occasionally a helpful clergyman will give both dates.
If a year of birth only is shown, it has probably been calculated from the age on one or more census records or from the age at marriage or death in a parish record or certificate.
The provenance of all dates can be found in the individual reports.
At the moment there is just one date, the burial of Mary Hunt, which has a double year because of the calendar change. Information about the change can be found here on Wikipedia
