<div dir="ltr">It's even more complicated than that: Lady Day Dating and the Julian/Gregorian Calendar are two separate things. Here's how I explained the difference to myself, which later went into a Folger blog post:<blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">It’s especially important for researchers working with British documents to remember that Lady Day dating (affecting year numbering every 1 January through 24 March) and the Julian calendar (affecting day numbering year round) are separate because they were not modernized at the same time. Scotland officially dropped Lady Day dating after 31 December 1599, which was followed by 1 January 1600, but continued to use the Julian calendar until Wednesday 2 September 1752, which was followed by Thursday 14 September 1752. England and Wales also switched from the Julian calendar in September 1752, but had already modernized year numbering the previous January (31 December 1751 was followed by 1 January 1752).</blockquote><div>See <a href="https://www.folger.edu/blogs/collation/untangling-dating/" target="_blank">https://www.folger.edu/blogs/collation/untangling-dating/</a> for the whole post.</div><div><br></div><div>Short version: if you've got an English imprint with an exact day and year, and the day was within 1 January and 24 March, and the year was 1751 or earlier, add one to the year.</div><div><br></div><div>Erin<br><div><br></div><div><br></div><div><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><p class="MsoNormal"><a name="m_-7417732148363502406_SignatureSanitizer__MailAutoSig"><span style="font-size:7.5pt;font-family:"Arial",sans-serif">______________________<br></span></a><a name="m_-7417732148363502406_SignatureSanitizer__MailAutoSig"><span style="font-size:7.5pt;font-family:"Arial",sans-serif">Erin Blake, Ph.D. | Senior Cataloger | Folger

<p class="MsoNormal">I am working on some English political pamphlets primarily from the 1640s. Most of the records I have found in OCLC take the year as given on the piece, but in some cases the ESTC records have noted that Lady day dating has been used, while
entries that exist in Wing take the date as given. I have not dealt with Lady day dating to this point, so I’m wondering if I should assume that it applies to everything printed before the region of origin adopted the Gregorian calendar or only take it into
account when specified in a union list or some other reference source? At this point I can’t tell if I am overthinking or what and I would be glad for clarification on this. Thanks,<u></u><u></u></p>
