{ "_id": "6acb7d76fe5cc25786e90bdf", "Package": "jalcal", "Type": "Package", "Title": "Convert Between Jalaali (Persian or Solar Hijri) and Gregorian\nCalendar Dates", "Description": "The Jalaali calendar, also known as the Persian or Solar\nHijri calendar, is the official calendar of Iran and\nAfghanistan. It starts on Nowruz, the spring equinox, and\nfollows an astronomical system for determining leap years. Each\nyear consists of 365 or 366 days, divided into 12 months. This\npackage provides functions for converting dates between the\nJalaali and Gregorian calendars. The conversion calculations\nare based on the work of Kazimierz M. Borkowski (1996)\n(), who used an analytical model of\nEarth's motion to compute equinoxes from AD 550 to 3800 and\ndetermine leap years based on Tehran time.", "Version": "0.3.0", "Date": "2025-03-20", "Authors@R": "c(\nperson(given = \"Abdollah\", family = \"Jalilian\",\nemail = \"stat4aj@gmail.com\",\nrole = c(\"aut\", \"cre\"),\ncomment = c(ORCID = \"0000-0002-6573-0069\")\n),\nperson(given = \"Kazimierz M.\", family = \"Borkowski\",\nrole = \"ctb\"\n)\n)", "Maintainer": "Abdollah Jalilian ", "License": "GPL (>= 2)", "Encoding": "UTF-8", "RoxygenNote": "7.3.2", "URL": "https://github.com/jalilian/jalcal", "BugReports": "https://github.com/jalilian/jalcal/issues", "Repository": "https://jalilian.r-universe.dev", "Date/Publication": "2025-04-09 11:24:47 UTC", "RemoteUrl": "https://github.com/jalilian/jalcal", "RemoteRef": "HEAD", "RemoteSha": "3ec4eff16dbf3c2161ba01f47606af204e03a0b4", "NeedsCompilation": "no", "Packaged": { "Date": "2026-10-11 12:11:41 UTC", "User": "root" }, "Author": "Abdollah Jalilian [aut, cre] (ORCID:\n),\nKazimierz M.
