observance. It fixed the pantheon of major divinities, and also ensured that their names were uttered often, since at every Zoroastrian act of worship the yazatas of both day and month were invoked. It also clarified the pattern of festivities; for example, Mitrakanna or <a href="/wiki/Mehregan" title="Mehregan">Mehregan</a> was celebrated on Mithra day of Mithra month, and the Tiri festival (Tiragan) was celebrated on Tiri day of the Tiri month. </p><p>In 538 BC <a href="/wiki/Cyrus_the_Great" title="Cyrus the Great">Cyrus the Great</a> (uncertain if he was a Zoroastrian) conquered Babylon and the Babylonian luni-solar calendar came into use for civil purposes. <a href="/wiki/Cambyses_II" title="Cambyses II">Cambyses</a> conquered Egypt in 525 BC. He was accompanied by <a href="/wiki/Darius_the_Great" title="Darius the Great">Darius</a>, a Zoroastrian who became ruler of the Persian empire in 517 BC. The Zoroastrians adopted the wandering Egyptian solar calendar of twelve months of thirty days plus five <a href="/wiki/Intercalation_(timekeeping)#Solar_calendars" title="Intercalation (timekeeping)">epagomenal days</a>. As their year began in the spring (with the festival of <i>norouz</i>) the <i>epagomenai</i> were placed just before <i>norouz</i>. </p><p>In Egypt the star Sirius had significance since every 1460 years (the <a href="/wiki/Sothic_cycle" title="Sothic cycle">Sothic cycle</a>) its <a href="/wiki/Heliacal_rising" title="Heliacal rising">heliacal rising</a> (just before sunrise) marked the Egyptian new year and the inundation of the Nile. In Persia also the star had significance, since its heliacal rising there also coincided with the coming of the rain. The fourth Persian month was <i>Tishtrya</i> (Sirius, rain star). The vernal equinox at Greenwich fell on the first day of the first month from 487 to 483 BC (inclusive).

In the first year the people carried on using the old calendar, anticipating festival dates by five days. As each day is named after a god, it is important to observe the celebrations on the right day. Thus the <i>fravasis</i> festival, which in the old calendar was kept between sunset on 30 Spandarmad and sunrise on 1 Frawardin, was now observed throughout the <i>epagomenai</i>. In the second year of the reform, the old 30 Spandarmad was the new 25 Spandarmad, so from then on the festival covered eleven days, up to the new 1 Frawardin. Five days was considered enough for other festivals, however. </p><p>In all the lands where the Persian calendar was used the <i>epagomenai</i> were placed at the end of the year. To offset the difference between the agricultural year and the calendar year (the tax-gathering season began after the harvest) the start of the <i>araji</i> (land-tax) year was delayed by one month every 120 years. A Roman historian, Quintus Curtius Rufus, describing a ceremony in 333 BC, writes: </p> <blockquote><p>The magi were followed by three hundred and sixty-five young men clad in purple robes, equal in number to the days of a whole year; for the Persians also divided the year into that number of days.<sup id="cite_ref-6" class="reference"><a href="#cite_note-6"><span class="cite-bracket">[</span>6<span class="cite-bracket">]</span></a></sup></p></blockquote> <p>After the conquests by <a href="/wiki/Alexander_III_of_Macedon" class="mw-redirect" title="Alexander III of Macedon">Alexander the Great</a> and his death, the Persian territories fell to one of his generals, <a href="/wiki/Seleucus_I_Nicator" title="Seleucus I Nicator">Seleucus</a> (312 BC), starting the <a href="/wiki/Seleucid" class="mw-redirect" title="Seleucid">Seleucid</a> dynasty of Iran. Based on the Greek tradition, Seleucids introduced the practice of dating by era rather than by the reign of individual kings. Their era became known as that of Alexander, or later the <a href="/wiki/Seleucid_era" title="Seleucid era">Seleucid era</a>. Since the new rulers were not Zoroastrians, Zoroastrian priests lost their function at the royal courts, and so resented the Seleucids. Although they began dating by eras, they established their own era of Zoroaster. </p><p>That was the first serious attempt to determine the dates associated with the prophet Zoroaster's life. Priests had no Zoroastrian historical sources, and so turned to Babylonian archives famous in the ancient world. From these they learned that a great event in Persian history took place 228 years before the era of Alexander. In fact, this was the conquest of <a href="/wiki/Babylon" title="Babylon">Babylon</a> by Cyrus the Great in 539 BC. But the priests misinterpreted this date to be the time the "true faith" was revealed to their prophet, and since <a href="/wiki/Avestan" title="Avestan">Avestan</a> literature indicates that revelation happened when Zoroaster was 30 years old, 568 BC was taken as his year of birth. The date entered written records as the beginning of the era of Zoroaster, and indeed, the <a href="/wiki/Achaemenid_Empire" title="Achaemenid Empire">Persian Empire</a>. This incorrect date is still mentioned in many current encyclopedias as Zoroaster's birth date. </p> <div class="mw-heading mw-heading4"><h4 id="Modifications_by_Parthians,_Ardashir_I,_Hormizd_I,_Yazdgerd_III"><span id="Modifications_by_Parthians.2C_Ardashir_I.2C_Hormizd_I.2C_Yazdgerd_III"></span>Modifications by Parthians, Ardashir I, Hormizd I, Yazdgerd III</h4><span class="mw-editsection"> <a role="button" href="/w/index.php?title=Iranian_calendars&action=edit&section=5" title="Edit section: Modifications by Parthians, Ardashir I, Hormizd I, Yazdgerd III" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> <span class="minerva-icon minerva-icon--edit"></span> <span>edit</span> </a> </span> </div> <p>The <a href="/wiki/Parthia" title="Parthia">Parthians</a> (Arsacid dynasty) adopted the same calendar system with minor modifications, and dated their era from 248 BC, the date they succeeded the Seleucids.

Khayyam and his team had worked 8 years in <a href="/wiki/Isfahan" title="Isfahan">Isfahan</a>, the capital of Iran during the <a href="/wiki/Seljuq_dynasty" class="mw-redirect" title="Seljuq dynasty">Seljuq dynasty</a>. The research and creation of the Khayyam calendar was financially supported by Jalal Al din Shah. Khayyam designed his calendar in which the beginning of the new year, season and month are aligned and he named the first day of the spring and the new year to be Norooz (also spelled <a href="/wiki/Nowruz" title="Nowruz">Nowruz</a>). Before Khayyam's calendar, Norooz was not a fixed day and each year could fall in late winter or early spring. </p><p>From 15 March 1079, when the calendar had slipped a further eighteen days, the <i>araji</i> calendar was reformed by repeating the first eighteen days of Frawardin. Thus 14 March was 18 Frawardin <i>qadimi</i> (old) or <i>farsi</i> (Persian) and 15 March was 1 Frawardin <i>jalali</i> or <i>maleki</i> (royal). This new calendar was astronomically calculated, so that it did not have <i>epagemonai</i> – the months began when the sun entered a new sign of the zodiac. </p><p>About 120 years after the reform of AD 1006, when the vernal equinox was starting to fall in Ardawahisht, Zoroastrians made it again coincide with <i>nowruz</i> by adding a second Spandarmad. This <i>Shensai</i> calendar was a month behind the <i>qadimi</i> still used in Persia, being used only by the Zoroastrians in India, the Parsees. On 6 June 1745 (<a href="/wiki/Old_Style_and_New_Style_dates" title="Old Style and New Style dates">Old Style</a>) some <a href="/wiki/Parsee" class="mw-redirect" title="Parsee">Parsees</a> re-adopted the <i>qadimi</i> calendar, and in 1906 some adopted the <i>Fasli</i> calendar in which 1 Frawardin was equated with 21 March, so that there was a sixth epagomenal day every four years. In 1911 the <i>jalali</i> calendar became the official national calendar of Persia. Some Zoroastrians in Persia now use the <i>Fasli</i> calendar, having begun changing to it in 1930. </p> <div class="mw-heading mw-heading3"><h3 id="Modern_calendar:_Solar_Hijri_(SH)"><span id="Modern_calendar:_Solar_Hijri_.28SH.29"></span>Modern calendar: Solar Hijri (SH)</h3><span class="mw-editsection"> <a role="button" href="/w/index.php?title=Iranian_calendars&action=edit&section=8" title="Edit section: Modern calendar: Solar Hijri (SH)" class="cdx-button cdx-button--size-large cdx-button--fake-button cdx-button--fake-button--enabled cdx-button--icon-only cdx-button--weight-quiet "> <span class="minerva-icon minerva-icon--edit"></span> <span>edit</span> </a> </span> </div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Solar_Hijri_calendar" title="Solar Hijri calendar">Solar Hijri calendar</a></div> <p>The present Iranian calendar was legally adopted on 31 March 1925, under the early <a href="/wiki/Pahlavi_Iran" title="Pahlavi Iran">Pahlavi dynasty</a>.
