Store description excerpt

See today’s date in Gregorian, Hebrew, Islamic, Chinese, Maya, and more: all on one screen. Almaniac is built for people who want more than a basic A↔B date converter: native scripts, obscure calendars, real context, and a layout you can customize. SEE EVERYTHING AT ONCE: NOT ONE PAIR AT A TIME Most calendar apps make you pick two systems and convert back and forth. Almaniac shows the same date across every calendar you care about in a single scrollable list. Compare civil, religious, historical, and astronomical calendars side by side without tapping through screens. NATIVE SCRIPTS, DONE RIGHT Dates aren’t crammed into plain Latin. Almaniac renders Arabic, Hebrew, Chinese, Japanese, Devanagari, Bengali, Persian, and more with proper typography and layout. Prefer reading in English? Turn on transliteration and keep the native text visible too. 20 CALENDARS: INCLUDING ONES OTHER APPS SKIP • Gregorian & Julian • Hebrew (Jewish) • Islamic — tabular and Umm al-Qura (Saudi official) • Chinese, Japanese Wareki & Minguo • Persian (Solar Hijri) • Ethiopian & Coptic • Thai Buddhist, Bengali & Indian Civil • Baháʼí & ISO Week Date • Maya with Long Count • French Republican, Soviet Revolutionary & Discordian • Julian Day (astronomical dating) If you’ve looked for French Republican Calendar, Soviet Revolutionary, Discordian, Wareki, or a proper Maya Long Count in other apps... this is what they usually don’t include. ISLAMIC DATES THAT MATCH REAL-WORLD USE Many converters only offer a simple tabular Hijri approximation. Almaniac lets you switch between tabular arithmetic and Umm al-Qura, plus a ±1 day adjustment for local moon-sighting practice — closer to how people actually use Islamic dates. ACTUALLY LEARN EACH CALENDAR Tap any row for a deep dive: history, how the system works, calendar type, and world adoption maps with a historical timeline slider. Illustrated banners and sourced imagery, not just a number in a text field. RELIGIOUS HOLIDAYS ON THE DATE YOU’RE VIEWING See major Christian, Jewish, and Islamic observances for whatever day you’re exploring - useful for interfaith seasons, travel, and “is that a holiday?” moments other converters ignore entirely. JUMP TO ANY DATE WITH SMART PICKERS Search calendars, convert eras, and enter dates the way each system expects: including Maya fields, BC/AD, and calendar-specific inputs. Step by day or month, or jump straight to today. YOUR DASHBOARD, YOUR WAY Show, hide, and drag to reorder calendars. Copy any date. Open a fullscreen view for long or complex dates. Choose light/dark mode and Distinct, Mono, or Sepia themes. Pick a home screen icon that fits your launcher. HOME SCREEN WIDGET Glance at today across your chosen calendars without opening the app - something most converter tools don’t offer at all. PHONE & TABLET Clean, readable layout on small screens and large ones. Bold per-calendar colors (or monochrome if you prefer) so you can scan fast. Whether you’re tracking
