title="Påske">påskehøytiden</a> i et gitt år. På latin og engelsk kalles prosedyren for <i>Computus</i> og har siden tidlig <a href="/wiki/Middelalderen" title="Middelalderen">middelalder</a> vært svært betydningsfull, da datoene for store deler av <a href="/wiki/Kirke%C3%A5ret" title="Kirkeåret">kirkeåret</a> bestemmes ut fra dette tidspunktet. Ordet <i>«computer»</i> (<i>«komputist»</i> på norsk) betydde opprinnelig en person som var i stand til å regne ut påsketidspunktet. Komputistene kan på mange måter betraktes som forløperne til den nyere tids matematikere. De mest kjente komputistene fra middelalderen er <a href="/wiki/Dionysius_Exiguus" title="Dionysius Exiguus">Dionysius Exiguus</a> (Denys le Petit) og <a href="/wiki/Beda_den_%C3%A6rverdige" title="Beda den ærverdige">Beda den ærverdige</a>. </p> <meta property="mw:PageProp/toc" /> <div class="mw-heading mw-heading2"><h2 id="Definisjon">Definisjon</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=P%C3%A5skeformelen&veaction=edit&section=1" title="Rediger avsnitt: Definisjon" class="mw-editsection-visualeditor"><span>rediger</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=P%C3%A5skeformelen&action=edit&section=1" title="Rediger kildekoden til seksjonen Definisjon"><span>rediger kilde</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>I de fleste oppslagsverk finner man regelen formulert som følger: </p> <dl><dd>Første <a href="/wiki/P%C3%A5skedag" title="Påskedag">påskedag</a> faller på første <a href="/wiki/S%C3%B8ndag" title="Søndag">søndag</a> etter første <a href="/wiki/Fullm%C3%A5ne" title="Fullmåne">fullmåne</a> på eller etter vår<a href="/wiki/Jevnd%C3%B8gn" title="Jevndøgn">jevndøgn</a>.</dd></dl> <p>Imidlertid gir en slik regel stort rom for ulike tolkninger, blant annet hvordan <a href="/wiki/P%C3%A5ske" title="Påske">påskens</a> tidspunkt da vil avhenge av hvor man befinner seg på <a href="/wiki/Jorden" title="Jorden">jordkloden</a> i forhold til <a href="/wiki/Datolinjen" title="Datolinjen">datolinjen</a> og andre astronomiske forhold, som detaljkunnskaper om <a href="/wiki/M%C3%A5nen" title="Månen">månens</a> bane og hvilken geografisk <a href="/wiki/Lengdegrad" title="Lengdegrad">lengde</a> den observeres fra. </p><p>Den <b>kanoniske definisjonen</b> av påskedatoen kom <a href="/wiki/Konsilet_i_Nikea" title="Konsilet i Nikea">konsilet i Nikea</a> frem til i året <a href="/wiki/325" title="325">325</a>:<br /> </p> <dl><dd>«Påsken er den søndagen som følger den fjortende dagen til den månen som oppnår denne alderen på den 21. mars eller umiddelbart deretter.»</dd></dl> <p>Av definisjonen fremgår det at påsken ikke fastsettes i forhold til det astronomiske vårjevndøgn, men til en fast kalenderdato. Denne ligger riktignok nær det astronomiske vårjevndøgnspunktet, men faller likevel aldri helt sammen med dette. Herav fremgår det også at påsketidspunktet ikke fastsettes i forhold til fullmånen, men til nymånen som opptrer 8. mars eller umiddelbart deretter. «Månens alder» angir det antall dager som er gått siden <a href="/wiki/Nym%C3%A5ne" title="Nymåne">nymåne</a>. Videre er det ikke den virkelige månen, som har en svært komplisert bane, men en tenkt middelmåne som går med jevn fart i banen sin rundt jorden. </p><p>Fullmånen som går forut for tidspunktet for påskehøytiden er gjennom tidene (også etter <a href="/wiki/Den_julianske_kalenderen" title="Den julianske kalenderen">den julianske kalenderen</a>) blitt kalt for <b>påskefullmånen</b>. </p><p>Påskedatoen som de to settene med påskeformler under gir i hver sin periode er blitt brukt i de fleste vesteuropeiske land siden kristendommen ble innført og altså etter kirkemøtet i Nikea i <a href="/wiki/325" title="325">325</a>. Fordi påskedatoen er gjort uavhengig av lengdegrad og den virkelige månens bevegelse, oppnår man dermed en dato som er lik for alle, og som lett kan beregnes for et hvilket som helst fremtidig eller tidligere tidspunkt, uten at det er nødvendig å foreta noen faktiske måneobservasjoner. I jødedommen benytter man imidlertid en annen formel. </p><p>For å beregne påskedatoen trenger man derfor en «evigvarende månekalender» som går ut fra denne tenkte middelmånen som kalles <i>den eklesiastiske månen</i>. Denne regnemåten heter «Computus Eclesiasticus».

Denne er viktig for historiske undersøkelser. Den opprinnelige påskeformelen ble først utarbeidet av Denis le Petit på 500-tallet. På 700-tallet publiserte så engelskmannen Beda boken <i><a href="/wiki/De_temporum_ratione" title="De temporum ratione">De temporum ratione</a></i>, som ble brukt som standard læreverk på dette området gjennom hele middelalderen. </p><p>I de fleste <a href="/wiki/Den_ortodokse_kirke" title="Den ortodokse kirke">ortodokse kirkene</a> baseres påskeformelen fortsatt på den julianske kalenderen. Siden landene vanligvis bruker <a href="/wiki/Den_gregorianske_kalenderen" title="Den gregorianske kalenderen">den gregorianske kalenderen</a> som sin borgerlige kalender, betyr det at påskedagen vil ligge i tidsrommet 4. april – 8. mai i perioden 1900 – 2099. (Forskjellen mellom den julianske og den gregorianske kalenderen øker med tre døgn i løpet av 400 år.) </p><p><a href="/wiki/M%C3%A5nekalender" title="Månekalender">Månekalenderen</a> som ligger til grunn for påskeformelen bygger på en syklus på 532 år <span class="nowrap">(19 × 28 år)</span> (<a href="/wiki/Gyldentall" title="Gyldentall">Metons syklus</a> × <a href="/wiki/Solsyklus" title="Solsyklus">solsyklus</a>) (dvs. 6 384 måneder, 27 759 uker = 194 313 døgn). Månesyklusen bygger på det fra gammelt av kjente faktum at den <a href="/wiki/Gyldentall" title="Gyldentall">synodiske månen</a> gjennomfører nokså nøyaktig 235 omløp i løpet av 19 julianske år (ett juliansk år består av 365¼ døgn). Denne 19-årige månesyklusen er kjent fra den greske astronomen Meton og kalles etter ham for <i>Metons syklus</i>. Den 28-årige solsyklusen er satt sammen av den 4-årige skuddårssyklusen og den 7-årige ukedagssyklusen. </p><p>Som <b>begynnelsesår</b> for denne 532-årige påskesyklusen valgte man <a href="/wiki/Skudd%C3%A5r" title="Skuddår">skuddåret</a> <a href="/wiki/608" title="608">608</a> e.Kr. (påskedag var 7. april). Dette årets første nymåne kom 23. januar og året fikk tildelt <a href="/wiki/Gyldentall" title="Gyldentall">gyldentallet</a> <b>1</b>. I dette året falt 1. januar på en mandag. Året var tildelt <a href="/wiki/S%C3%B8ndagsbokstav" title="Søndagsbokstav">søndagsbokstavene</a> <b>G</b> og <b>F</b>. Går man herfra 532 år fremover i tid til året <a href="/wiki/1140" title="1140">1140</a> e.Kr., så finner man at sistnevnte år har nøyaktig det samme gyldentallet <b>1</b> og søndagsbokstavparet <b><span class="nowrap">G<small> </small>F</span></b> som det førstnevnte (og dermed påskedag 7. april). Dette er fordi den samme kombinasjonen av gyldentall og søndagsbokstaver alltid gjentar seg efter 532 år, men ikke før.
