Flutter needs a package. Most bugs come from storing Hijri strings and from ignoring edge cases, not from the conversion itself.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">This guide walks through the decisions, the platform options, the common mistakes, and a testing checklist.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"i\"><\/span><span style=\"font-weight: 400;\">What Is the Hijri Calendar, and Why Do Saudi Apps Need It?<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The Hijri calendar is a lunar calendar with 12 months of 29 or 30 days. Its year is about 354 or 355 days, roughly 11 days shorter than the Gregorian year. Umm al-Qura is the Hijri calendar Saudi Arabia uses for official and administrative purposes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The twelve months are Muharram, Safar, Rabi al-Awwal, Rabi al-Thani, Jumada al-Awwal, Jumada al-Thani, Rajab, Shaban, Ramadan, Shawwal, Dhu al-Qadah, and Dhu al-Hijjah. Your app needs correct Arabic and English labels for each one.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Many Saudi users read dates in both systems. Government forms, official documents, school calendars, and contracts often show Hijri and Gregorian dates side by side. An app that shows only Gregorian dates can feel incomplete in these settings.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Hijri dates matter most in these app types:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Government and legal apps that process forms and deadlines<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Education platforms with term dates and exam schedules<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Banking and Islamic finance apps with payment and contract dates<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">HR and payroll tools that track leave and employment dates<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Healthcare apps with appointments and patient records<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Retail apps that run Ramadan and Eid campaigns<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">If you are building for the Kingdom, Hijri support belongs in discovery, alongside Arabic layout and numerals.

Each one changes your data model.<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Pick the calendar variant. For Saudi users, use Umm al-Qura. Other Hijri variants can differ by a day.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Decide how dates appear. Show Hijri only, show both, or let users switch.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Choose your storage format. Store dates as Gregorian or UTC timestamps. Convert for display.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Set language and numerals. Choose Arabic-Indic digits (\u0660\u2013\u0669) or Western digits (0\u20139), and apply the rule everywhere.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Handle religious dates separately. Umm al-Qura is a calculated civil calendar. The start of Ramadan and the Eids can depend on moon sighting, and they may differ by a day.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">That last point matters for any app that shows religious events. Treat those dates as editable content, not as fixed calculations.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"i-3\"><\/span><span style=\"font-weight: 400;\">Step by Step: Add a Hijri Calendar to a Mobile App<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Follow this order to keep the work clean.<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Define your data model.

The hijri_picker package, for example, lets Flutter&#8217;s built-in Material 3 date picker show Hijri dates. It needs Flutter 3.32 or newer. The material_drum_picker package offers a Hijri mode for date, time, and date-time pickers, and it states that its built-in lunar calendar is Umm al-Qura.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Packages change fast. Before you commit, check the latest version, the Flutter requirement, and open issues. One picker package even documents a crash when you use a year picker with a non-Gregorian calendar and skip a required setting. Small details like this decide whether a package fits your project.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">If you work in Flutter, you can often reuse the same Hijri logic on both iOS and Android. That can save time compared with building separate native pickers.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"i-5\"><\/span><span style=\"font-weight: 400;\">How Hijri Dates Fit Common App Features<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The calendar touches more than the date picker. Think through each feature that uses dates.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Appointments and bookings. Save one UTC time. Show the Hijri label next to the Gregorian one. Reminders should follow the stored time.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Subscriptions and billing. Hijri months have 29 or 30 days, and the Hijri year is shorter than the Gregorian year. A Hijri anniversary shifts earlier each Gregorian year, so confirm which calendar your contracts use.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">HR leave and contracts. Check whether company policy counts in Hijri or Gregorian terms before you code the rules.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Reports and exports. Label the calendar in column headers, and let users choose one or both.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Search and filters. Filter by timestamp ranges. When a user picks a Hijri month, convert its first and last day into timestamps.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Here is the flow in plain terms. A user picks a Hijri date in the picker. The app converts it to a UTC timestamp and saves it. Later, the app converts that same timestamp back for display. One stored value can appear as Hijri on one screen and Gregorian on another, with no data conflicts.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"i-6\"><\/span><span style=\"font-weight: 400;\">Display Hijri Dates Without Confusing Users<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">A calendar that is technically correct can still confuse people. Use these design rules:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Label the calendar. Show &#8220;Hijri&#8221; or &#8220;\u0647\u0640&#8221; next to the date.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Show both when it helps. Pair Hijri and Gregorian dates on forms and receipts.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Keep the order consistent. Do not swap day, month, and year between screens.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Respect right-to-left layouts. Mirror the calendar grid, month arrows, and week order.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Use one numeral style. Mixed digits make dates hard to scan.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Working on Saudi projects shapes these choices.

Its effort depends on your platform, how many screens show dates, and whether you need a custom picker. Apps with many forms, bookings, or reports need more work than apps that show a single date.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To see how localization affects total budgets, read our guide to<\/span><a href=\"https:\/\/thehashtech.com\/blog\/how-much-does-mobile-app-development-cost-in-saudi-arabia\/\"> <span style=\"font-weight: 400;\">mobile app development cost in Saudi Arabia<\/span><\/a><span style=\"font-weight: 400;\">. Ask any vendor to list Hijri support as a separate line item in the estimate.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"i-10\"><\/span><span style=\"font-weight: 400;\">Final Thoughts<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Learning how to add a Hijri calendar to a mobile app is mostly about discipline. Pick Umm al-Qura. Store standard timestamps. Convert only for display. Label calendars clearly. And treat religious dates as content you can edit, not constants you calculate once.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Done well, Hijri support makes your app feel built for Saudi users instead of adapted for them. Plan it early, test it with real dates, and keep it in your estimate from the start.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"i-11\"><\/span><span style=\"font-weight: 400;\">Frequently Asked Questions<\/span><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span style=\"font-weight: 400;\">Can I add a Hijri calendar to a mobile app without a library?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Yes, on native platforms. iOS includes calendar identifiers for Islamic calendars, and Android includes Hijrah date classes and ICU calendar tools. A library helps most when you need a ready-made Hijri date picker, especially in Flutter or React Native.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Which Hijri calendar should a Saudi app use?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Use Umm al-Qura. It is the calendar Saudi Arabia uses for official and administrative purposes. Other Hijri calculations can differ by a day.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Why do Hijri dates sometimes differ by one day?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Different calendar variants calculate month starts differently. Also, religious observances such as Ramadan and Eid can depend on moon sighting, so they may not match a calculated calendar.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Should I store dates as Hijri or Gregorian?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Store dates as Gregorian or UTC timestamps. Convert them to Hijri only when you display them. This keeps sorting, filtering, and time zones reliable.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Does Flutter support a Hijri date picker?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Yes, through packages. Options include hijri_picker, which adapts Flutter&#8217;s Material 3 date picker, and a drum-style picker with a Hijri mode. Check each package&#8217;s Flutter version requirement and open issues before you choose.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Do I need Hijri dates in every Saudi app?<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Not always. They matter most in government, education, finance, HR, healthcare, and legal apps. For other apps, you can offer them as a user setting.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Technical details are based on platform documentation and public package pages for hijri_picker and material_drum_picker.
