Why does a date differ from another calendar app?
Mahbanou starts each Persian year the way Iran's official Calendar Center does: from the moment of the March equinox against true noon on the 52.5° E meridian, worked out from NASA JPL's ephemeris. Many apps use a leap-year formula instead, which gets some years wrong (1404 among them).
Which Zoroastrian calendar should I choose?
Shahenshahi is kept by most Parsis (new year in August), Kadmi a month ahead of it (July), Parsi Fasli starts on 21 March, and the Iranian (Bastani) calendar starts on Nowruz. Turn on Zoroastrian calendar in Settings and pick one or more; Shown first chooses the one that leads.
How are the gah times worked out?
From sunrise and sunset at your place (Settings › Place). Gah times can follow the Parsi priests' clock (local mean time) or true solar noon as in Iran; Automatic picks by your leading calendar. From Avan mah to the Gathas, Rapithwin gives way to Second Havan. Start the roj at Hoshbam starts Havan 36 minutes before sunrise.
Reminders don't arrive.
If you chose quiet delivery on first launch, reminders arrive silently in Notification Center, with no banner or sound: tap Turn on alerts in Mahbanou's Settings › Reminders. If notifications are off, allow them for Mahbanou in the iOS Settings app, then turn the reminders on in Mahbanou's Settings. The app schedules the coming weeks and tops them up whenever it opens, so open it now and then.
What are nabor reminders?
Nabor days are the meat-free roj: Bahman, Mohor, Gosh and Ram roj in each mah of the Zoroastrian calendar shown first, marked with a green leaf. Turn on Nabor days in Settings › Reminders (or on the welcome's reminder step) for a note on the morning of each one, at your reminder time. If Each morning's roj is on too, the nabor note is folded into that morning's roj note, so you get one note, not two. Nabor reminders are off until you turn them on.
How do I add a widget or a watch complication?
On the Home Screen or Lock Screen, touch and hold, tap Edit or Customize, then add Mahbanou's Today, Gah or Coming up widget. On Apple Watch, edit a watch face and choose Mahbanou for a complication.
How do I start over?
Settings › Reset settings puts every setting back as on a new install and opens the welcome again, where you choose your language, calendar, style, reminders and place.
The Apple Watch shows old settings.
The watch gets its settings from the iPhone. Open Mahbanou on the iPhone with the watch nearby and change any setting to send them again.
