## What is Bahá’í Calendar?

A unified calendar for a coherent Bahá’í life.

This is a Bahá’í Calendar for personal and professional time-management, planning and reference. It uses your existing calendars accounts, like Apple / iCloud, iCal, Google, Outlook etc.., so all events also appear on any Mac, PC or other device that use the same accounts. The Badí (Bahá’í) calendar is shown with the Gregorian calendar, or the calendar from your region, culture or country (through settings). This makes it easy to unite the routines and spirit of a Bahá’í daily life, with the daily planning and scheduling requirements of work, school and social life in general.

Bahá’í holydays (with local times), periods and feasts are clearly marked with colors and text. Graphical elements and coloring are used as educational elements to indicate sunset and seasons (each have their specified color). 

The 4 seasons goes like a colored thread through the year, according to the "Badí calendar" which is the name of this unique solar calendar system: 3 white spring- months, 4 yellow summer-months, 6 green autumn-months, and 6 red winter-months.

Events added and edited in the Bahá’í Calendar app is part of the general system of notifications, meetings-invitations, Siri-control, maps etc. This app may thus accompany or even replace the built in calendar.


Functionality:

- Displays the system-date alongside the Bahá’í dates for a unified use
- Each calendar event is marked as a dot with the color of the calendar it belongs to (family, work, google, outlook...)
- Search for events
- Holydays, special periods and Nineteen Day Feasts are shown, and can also be populated as events into any of you calendar accounts.
- Select first day of the week: Jalál (Glory/Saturday), Sunday or Monday.
- Display the calendrical names in Arabic, English or System language (translations in progress)
- Holydays with specified times are calculated according to local sunset times of that day, and daylight saving
- Date-shifts and local sunrise/set times are calculated separately for each day, and thus follow natural seasonal variations
- Settings allow dates to shift at 6 in the evening in the northern regions of the world
- Seasons are illustrated with coloring, as given in the writings (3 x white, 4 x yellow, 6 x green, 6 x red)
- The Nineteen Day Feasts are marked with the color of the season 
- Additional date-info is shown to make it easier to see which events belong to which Bahá’í and system-dates
- 3D Touch actions supported for iPhone 6s and 6s Plus (and newer)
- Dates and holydays are strictly calculated according to the 50 years of dates published by The Universal House of Justice
- Dates beyond year 172-220 displays only system dates
- Works in both portrait and landscape
- The app language is english for now, but date-formats are still local  (translations are in progress)


Support development:

This app will never contain ads, require an account or collect your personal data, but it still requires months of dedicated development to create a professional-grade solution. By purchasing it, you not only get it for your own use, but also support and enable further development of e.g. a week view, reminders, more beautification, info behind the holydays, translations, Apple Watch integration, etc...


Plans and ideas for coming and future updates (in any order, and as time/revenue allows):

- Year view
- Week-view
- Utilize the larger space of iPad and iPhone Plus screens
- Translations
- iOS 8+ Widget
- Apple Watch
- Show, add and edit events using the Bahá’í dates alongside system dates
- Layout refinements and optimizations
- Performance enhancements
- More functionality and different ways to show the calendar, based on user feedback and devices/versions in use
...and more

The logo is created by the Norwegian photographer and designer Jens von Krogh, and represents the four seasons, with their colors and duration.

### 3/5 — Text so small

*2026-03-08*

The information is beautifully set up, but this is super tiny text with no apparent way to adjust size as needed.  We NEED the ability to enlarge it.  PLEASE make an update to do so.

### 5/5 — Thank You So Much

*2025-08-16*

This app is simply wonderful. It has everything you would need in regards to the Bahai calendar. It's easy to use and pretty straightforward, not to mention a clean user interface and so far no glitches. The hard work and dedication you put into this App has not gone unnoticed, thank you my brother and I will make sure I share this with as many people as I can. Alla U Abha

### 5/5 — Love it and use it…..

*2024-11-10*

I would gladly donate money as your hard work should be rewarded. Could the color of the tiny font be much darker and or the font size adjustable or bigger, but darker for sure please? In addition I would very much like if both the Arabic and English names of months could be displayed together at the same time ie Bahá/Splendor, Jalál/Glory.

### 3/5 — Good but point size too small - very sad

*2024-08-06*

This is a beautifully arranged calendar and has a lot of valuable information.  However, it is not possible to adjust the point size of the dates, and the Gregorian dates are very light and very tiny, even on an iPad.  We wish that this would be updated so we can adjust point size across the whole calendar.

### 2/5 — Error

*2024-01-01*

Ayyamiha is 5 days in a leap year correct?  This calendar shows 4 days even though 2024 is a leap year.

### 5/5 — What we’ve been looking for!

*2023-09-11*

I kept saying how I wish there was an app that would give me all the future dates for holy days that rotate from year to year. This app provides that and so much more! Beautifully designed and integrates so well with Apple calendar. I’m telling All my friends about it. Well done and what a great service to the team that designed it 👍🏼

### 5/5 — great app❤️

*2023-01-30*

thank you for great app.please add persian language

### 5/5 — Thank you.

*2021-07-13*

Allah’u’Abha! This app is very handy! If I may make a request, would some widget functionality bea possibility? I use the Outlook and Gmail widgets and would love to also incorporate the Badi calendar on my Home Screen. Just a suggestion 😊😊

**Developer response:** Thanks for encouraging feedback! Feature requests are welcome, and widget(s) is a very good suggestion 😊.

Development takes a lot of time/resources, and this app has been "sleeping" for a long time, as I've had to prioritize work for income (there's not much will to pay for apps; and free apps is still an expense to maintain).

I'll try to find time to develop some updates — and perhaps realize the dream of a version 2. But I might have to add some in-app purchase, a subscription or something (but I will never have ads or collect and sell user-data, like so many other apps).

### 5/5 — Great Calendar App!

*2019-03-22*

I live the design of this. A great deal of thought, engineering and design work has gone into this to create a Badi Calendar app that syncs with all of my calendars (IOS calendar app and Google Calendars). Designing a calendar that adjusts the start of the day based on sunset couldn’t have been easy. Some of the fonts are quite small but necessary to make the calendar useful. I’m going to try to use this as my primary calendar, it’s that good.

**Developer response:** Heartwarming :). Thank you for insightful and encouraging feedback. I use it daily myself.. and long for time to bring it to the next level.

### 5/5 — This app is great

*2017-03-05*

Bahá'í dates start at sunset and end on the next day at sunset. This can make it tricky to map between Gregorian and Bahá'í dates; this app makes it super simple to translate between the two calendars.
