Welcome to this website which is dedicated to the synchronisation of the chronology and the entries of the Irish Annals.
This has been done by tabulating the chronological elements and the entries of the principal annals in parallel as was initially proposed in my paper 'The Chronology of the Irish annals' published in the Proceedings of the Royal Irish Academy, 98C(1998) pp. This paper remains the best published introduction to the ideas behind this synchronisation, and a copy of the paper is available online at the URL: Comprehensive examination of Irish chronicles reveals the existence of two distinct and contrasting chronological traditions.

The second tradition used a standardised list of the reigns of supposed 'kings of Ireland' as its chronological basis, and hence I term this the 'regnal canon tradition'.This tradition was initiated circa AD 1014 and continued in use up until AD 1685, and it is found in a remarkably wide range of literary forms, e.g.Here, we describe the case of a colorectal cancer (CRC) patient presenting with synchronous lung metastasis and metachronous thyroid, chest wall and urinary tract metastases over the course of 5 years.The chest wall metastasis was caused by needle tract seeding, implying a known time of onset.
