📅 The multi-calendar engine

Today, in every tradition.

Generic donation platforms run on one calendar: Gregorian. Alora Giving ships eight calendar-system plugins, driving 226 seeded observances across 10 traditions. Each calendar powers its own observance dates, seasonal campaign drafts, and dual-date display — so the right moment reaches the right community.

The eight calendar plugins, all native to the platform

Pick a calendar and the platform configures the observance list, the seasonal campaign cadence, and the date display. Mix calendars per affiliated organisation. Beyond the eight plugins, the observance library spans 10 traditions — 226 seeded observances, including Bahá'í, Jain, and Zoroastrian dates.

🏛️
Gregorian civil
The civil calendar

The shared civil baseline every other calendar is displayed alongside. Civic giving moments, national days, and the year-end window all live here.

Key windows: Q4 year-end giving (Nov–Dec), Giving Tuesday, tax-season receipts (Jan–Apr), civic anniversaries.

Why it matters: roughly 30% of giving arrives at year-end. The platform tracks the window and surfaces the year-end push as a draft campaign for your team to approve.

Example day
Sat, 16 May 2026 · day 136

Secular · fiscal
The fiscal calendar

Calendar year (Jan 1 – Dec 31) or fiscal-year variants per organisation: Jun 30 (AU/UK/IN), Mar 31, Sep 30 (US federal), Dec 31. Quarter-end appeal windows, mid-year updates, fiscal-year-end pushes.

Key windows: fiscal-year-end appeals (configurable), quarter-end reporting, annual statement cycles.

Why it matters: boards and auditors live on the fiscal year. Statements and campaign windows line up with your year-end — not just December's.

Example day
Q2 2026 · fiscal year configurable
Christian liturgical
The liturgical year

Advent → Christmas → Ordinary Time → Lent → Holy Week → Easter → Eastertide → Pentecost → Ordinary Time → Christ the King. Moveable feasts computed each year, with the Western/Orthodox Paschal split handled correctly.

Key seasons: Stewardship season (Oct–Nov), Christmas Eve, Easter Sunday, Pentecost, All Saints, Reformation Sunday.

Why it matters: Easter attendance is 2–4× a normal Sunday in most churches. The platform tracks the moveable feasts and surfaces each season as a draft campaign for staff approval — the year's highest-attention moments are never missed.

Example day
Sixth Sat of Easter · Eastertide
Hebrew lunisolar
The Jewish calendar

12 or 13 lunar months synchronised to the solar year via leap-month intercalation. Shabbat weekly. The festival cycle is anchored to Hebrew dates, not Gregorian approximations.

Key festivals: Rosh Hashanah, Yom Kippur, Sukkot, Simchat Torah, Hanukkah, Purim, Pesach, Shavuot, Tisha B'Av.

Why it matters: the High Holy Days (Rosh Hashanah + Yom Kippur + Kol Nidre) drive the majority of annual synagogue giving. The platform keys the appeal window to the Hebrew dates and surfaces it as a draft campaign ahead of the Days of Awe.

Example day
29 Iyar 5786 · Shabbat · day 44 of Omer
Islamic Hijri lunar
The Hijri calendar

12 lunar months, 354–355 days per year, drifting approximately 11 days earlier each Gregorian year. Dates resolved by Umm al-Qura-based calculation.

Key months: Ramadan (fasting + the last ten nights), Dhū al-Ḥijjah (Hajj + Eid al-Adha + first ten days), Muharram (new year + Ashura), Rabi al-Awwal (Mawlid).

Why it matters: Ramadan moves ~11 days earlier every Gregorian year — a March campaign this year needs to be a February campaign next. The platform recalculates automatically; your team never has to rebuild the calendar from scratch.

Example day
28 Dhū al-Qaʿdah 1447 · Pre-Hajj month
🕉
Hindu lunisolar
The panchanga engine

Festival dates resolved astronomically from the panchanga — lunar month, tithi, and paksha — with curated approximate dates as a fallback when a precise lunar anchor isn't defined. Every resolved date carries an honest precision label.

Key festivals: Diwali, Holi, Navaratri, Akshaya Tritiya, Janmashtami, Ganesh Chaturthi.

Why it matters: Akshaya Tritiya is traditionally the auspicious giving day in Hindu tradition, and like Diwali and Navaratri it moves with the lunisolar year. The platform computes the date and surfaces it as a seasonal campaign draft.

Example day
Vaiśākha (lunar month) · Akshaya window
Buddhist Era
The Buddhist calendar

Buddhist Era (BE) counted from Buddha's parinirvana — Gregorian year + 543/544. Lunar festival dates resolved per cycle; the observance library spans Theravada, Mahayana, and Vajrayana traditions.

Key festivals: Vesak / Buddha Purnima (full moon, May), Asalha Puja (Dharma Day), Vassa (three-month rain retreat), Kathina (robe-offering at retreat end).

Why it matters: Vesak (Buddha Purnima) is the highest dana occasion in Theravada tradition. The platform resolves the lunar full-moon date — which shifts each year — and drafts the appeal around it.

Example day
BE 2569 · Vesak season
Sikh · Nanakshahi
The Nanakshahi calendar

Fixed solar calendar with its era counted from Guru Nanak's birth (1469 CE). Months align to fixed Gregorian dates — Chet begins March 14, Vaisakh April 14 — so gurpurabs land predictably every year.

Key dates: Vaisakhi, Guru Nanak Gurpurab, Bandi Chhor Divas, Hola Mohalla.

Why it matters: Vaisakhi is the giving high point of the Sikh year. Vaisakhi-annual recurring gifts and the seasonal campaign draft key to it automatically — and monthly langar support runs on its own devotional schedule.

2 Jeth 558 NS
How the engine works

Calendar-aware, everywhere it matters

The calendar isn't a display option. It's wired into seasonal campaign drafting, page copy, date display, and devotional recurring schedules.

01

Seasonal draft campaigns

Upcoming observances — Pentecost, the High Holy Days, Dhū al-Ḥijjah, Akshaya Tritiya, Vesak, Vaisakhi — surface as draft campaigns in your dashboard. Vocabulary-correct, audience-segmented, ready for staff approval. Nothing auto-sends.

02

Season-aware copy

Donate-page banners and dashboard greetings reflect the active season for your organisation's configured tradition. Interfaith organisations run each program on its own calendar, with its own seasonal copy.

03

Honest dual-date display

Dates render in Gregorian and your tradition's calendar side by side — dual display, not a swap. Your accountant keeps civil dates; your community sees its own calendar on the giving surfaces.

04

Devotional recurring schedules

Recurring gifts can follow the tradition's clock — Jumu'ah weekly after Maghrib, Ramadan daily at iftar, Shabbat weekly at candle-lighting −18 minutes, Diwali and Vesak annually. Each charge is computed against the right calendar, every cycle.

05

Observance-window campaigns

Giving windows that straddle Gregorian months — Ramadan, the High Holy Days, stewardship season — are tracked as windows, so campaign goals and seasonal comparisons line up with the observance, not an arbitrary month boundary.

06

Expert-reviewed, honestly labeled

Festival lists, season descriptions, and appeal vocabulary go through the platform's SME review system — credentialed experts attest content, and anything still pending review is visibly labeled "cultural guidance under review."
