Monajjem is a calendar date converter capable of converting dates in 5 calendars: Bahá'í Era Persian Solar Muslim Lunar Christian/Gregorian and Jewish.

On start-up today's date is displayed in all 5 calendars. After entering a date tapping the corresponding calendar name causes the date to be converted and the equivalent dates in the other 4 calendars to be displayed. Tapping the Today button causes today's date to be displayed in all 5 calendars. Tapping the Next Day or the Previous Day button causes the displayed dates to advance or go back by one day respectively.

For the Bahá'í calendar the date of Naw-Rúz for the years 1 through 171 can be selected to be based on the Vernal Equinox in the Northern Hemisphere or to be March 21. For the Christian calendar the year in which the Gregorian reform was adopted can be selected to be 1582 or 1752. These options are only sampled when the Today button or one of the calendar names is tapped. Next and Previous Day buttons continue the existing conversion and ignore any changes in options.

For all calendars except the Bahá’í calendar years 1-9999 are supported. For the Bahá’í calendar years 1-250 are supported. If a date falls out of this range nothing will be displayed for that calendar.

Monajjem operates in landscape mode only.
