The Gregorian calculation of Easter was based on a method devised by the [[Calabria]]n doctor [[Aloysius Lilius]] (or Lilio) for adjusting the [[epact]]s of the Moon,<ref>G Moyer (1983), [http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?journal=grc..&year=1983&volume=book&page_ind=181 "Aloisius Lilius and the 'Compendium novae rationis restituendi kalendarium'"] {{Webarchive|url=https://web.archive.org/web/20211012082725/http://articles.adsabs.harvard.edu/cgi-bin/nph-iarticle_query?journal=grc..&year=1983&volume=book&page_ind=181 |date=12 October 2021 }}, pp. 171–188 in G.V. Coyne (ed.).</ref> and has been adopted by almost all Western Christians and by Western countries which celebrate national holidays at Easter. For the British Empire and colonies, a determination of the date of Easter Sunday using [[Golden number (time)|Golden Numbers]] and [[Dominical letter|Sunday letters]] was defined by the [[Calendar (New Style) Act 1750]] with its Annexe. This was designed to match exactly the Gregorian calculation.<ref name="legislation.gov.uk-calendar">{{cite web |title=Calendar (New Style) Act 1750 |url=https://www.legislation.gov.uk/apgb/Geo2/24/23 |website=legislation.gov.uk|access-date=23 April 2023|archive-date=April 23, 2023 |archive-url=https://web.archive.org/web/20230423123410/https://www.legislation.gov.uk/apgb/Geo2/24/23 |url-status=live }}</ref>
