El Dia Pi se celebra el 14 de març (en el format de calendari mes/dia, 3/14 que representen els tres dígits més representatius de la constant expressada en notació decimal). Val a dir doncs que, matemàticament parlant, no hi ha cap relació directa entre el nombre pi i el 14 de març, puix que els dígits 3, 1 i 4 en un cas venen donats per una representació en base 10 i en l&#39;altra per una representació mixta (sistema de dies i mesos) que no té res a veure amb la base 10. Tot i així, el 2009 la Cambra de Representants dels Estats Units va donar suport a la designació del dia Pi. El va crear Larry Shaw el 1989. El Dia de l&#39;aproximació de Pi se celebra el 22 de juliol (en el format de calendari dia/mes, 22/7, ja que aquesta fracció és una aproximació comuna a la constant). El Dia Pi de l&#39;any 2015 va tenir una significació especial pel fet que el 3/14/15 (data en format anglosaxó) a les 9:26:53 a.m. i p.m., amb la data i l&#39;hora es podien representar els 10 primers dígits de pi. El Dia Pi de l&#39;any 2018 va morir el físic teòric, cosmòleg i divulgador científic Stephen Hawking. El físic Albert Einstein també nasqué un 14 de març, el de 1879.</span><small> (ca)</small></span></li> <li style="display:none;"><span class="literal"><span property="dbo:abstract" lang="cs" >Den pí se slaví po celém světě každoročně 14. března na počest významné matematické konstanty tradičně značené π a nazývané Ludolfovo číslo.

Als Begründer dieser Tradition gilt Larry Shaw, der den Pi Day 1988 am Exploratorium in San Francisco initiierte, wo er seitdem jährlich begangen wird. 2009 wurde in den USA der 14. März vom US-Kongress zum offiziellen Nationaltag für die Kreiskonstante Pi erklärt. Der Pi-Tag wird traditionell mit dem gemeinsamen Verzehren von kreisförmigen Kuchen begangen (im Englischen wird der griechische Buchstabe π lautgleich wie das englische Wort pie, Kuchen, ausgesprochen). Ein solcher Kuchen von 20 Zentimeter Durchmesser hat zudem π Quadratdezimeter Grundfläche. Zur Verbreitung des Gedenktages trägt auch bei, dass zufällig der 14. März auch der Geburtstag Albert Einsteins und (seit 2018) der Todestag Stephen Hawkings ist. Besonders genaue Anhänger feiern um 13:59:26 Uhr und erreichen die Kreiszahl damit bis zur siebten Nachkommastelle (3/14 1:59:26 pm). Am Massachusetts Institute of Technology wurden 2015 in Anlehnung an den Pi-Tag einige Termine auf Samstag, den 14. März um 9:26 Uhr ET (3/14/15 9:26 am) gelegt. Mindestens seit dem Jahr 2000 wird auch ein Pi-Näherungstag (Pi Approximation Day) am 22.

UNESCO utropade under hösten 2019 14 mars till Internationella matematikdagen. Sedan tidigare har denna dag i många länder blivit en dag då matematik uppmärksammas på olika sätt av skolor, kommuner, organisationer och företag. Ett exempel är Google. I Sverige arbetar Sveriges Matematiklärarförening,, som nationell samordnare för stötta lärare, skolor, kommuner och andra organisationer för att ge bakgrund, idéer och inspiration om hur detta firande av matematikens dag kan gå till. Pi-approximationsdagen firas i vissa kretsar 22 juli eftersom 22/7 är en approximation av pi, något bättre än 3,14.</span><small> (sv)</small></span></li> <li style="display:none;"><span class="literal"><span property="dbo:abstract" lang="pt" >O Dia do Pi (π) e o Dia da Aproximação de Pi (π) são duas datas comemorativas em homenagem à constante π (pi).</span><small> (pt)</small></span></li> <li style="display:none;"><span class="literal"><span property="dbo:abstract" lang="ru" >День числа пи — неофициальный праздник, который отмечается любителями математики 14 марта в 1:59:26 в честь математической константы — числа пи. Этот праздник придумал в 1987 году физик из Сан-Франциско Ларри Шоу, который заметил, что в американской системе записи дат (месяц / число) дата 14 марта — 3/14 — и время 1:59:26 совпадает с первыми разрядами числа π = 3,1415926…Обычно празднуют в 1:59:26 дня (в 12-часовой системе), но придерживающиеся 24-часовой системы считают, что в этот момент время 13:59, и предпочитают отмечать праздник ночью. В этот день читают хвалебные речи в честь числа π, его роли в жизни человечества, рисуют антиутопические картины мира без π, пекут и едят «пи-рог» («Pi pie») с изображением греческой буквы «пи» или с первыми цифрами самого числа, пьют напитки и играют в игры, начинающиеся на «пи», решают головоломки и загадки, водят хороводы вокруг предметов, связанных с этим числом. Примечательно, что в этот же день родился Альберт Эйнштейн — создатель теории относительности, а также умер Стивен Хокинг. Празднуют также день приближённого значения π — 22 июля . Стоит отметить, что эта дата, записанная в виде дроби 22/7, точнее приближает число π, чем 3,14. При этом формат записи даты ДД/ММ или Д/М распространён гораздо шире, чем ММ.ДД, положенный в основу выбора даты 14 марта.</span><small> (ru)</small></span></li> <li style="display:none;"><span class="literal"><span property="dbo:abstract" lang="zh" >慶祝圓周率π的特別日子有兩天:圓周率日(英語:Pi Day,又译π节)和圓周率近似值日。</span><small> (zh)</small></span></li> <li style="display:none;"><span class="literal"><span property="dbo:abstract" lang="uk" >День пі — неофіційне свято, присвячене числу π. Воно святкується 14 березня, що в прийнятому в США форматі записується як 3.14, що є трьома першими розрядами числа π. Свято впроваджене на математичних факультетах значної кількості вишів у різних країнах. Зазвичай свято розпочинається о 1:59 ночі, що разом із датою складає перші шість знаків числа π (3,14159). Окрім того, цей день (14 березня) є також і днем народження Альберта Ейнштейна, що надає йому додаткової значущості в очах математиків. Досконалий День пі стався 14 березня 1592 року о 6 годині 53 хвилини та 58 секунд. Ця дата, записана в «американському» форматі, виглядає як 3/14/1592 6:53:58, що відповідає першим 12 знакам у числі π: 3,14159265358. Але, зважаючи на те, що того часу ще не було впроваджено ніякого стандартизованого , тим більше з потрібною точністю, скоріше за все цей момент ніким не святкувався. Приблизний День пі є однією з двох дат: або 22 липня (записується 22/7 — цей дріб дорівнює 3,14, що є приблизним виразом π), або 26 квітня (25 квітня високосного року) — день, коли Земля проходить дві астрономічні одиниці по своїй орбіті з початку календарного року: в цей день загальна довжина орбіти Землі, поділена на довжину вже пройденої ділянки, дорівнює π (тобто Земля пройшла в цей момент по своїй орбіті 2 радіани).</span><small> (uk)</small></span></li> </ul></td></tr><tr class="even"><td class="col-2"><a class="uri"
