Candra

Candra is a calendar and a journal in one, for people who keep their days by more than one calendar.

FIVE CALENDARS, ONE DAY • Weton: the seven-day week and the five-day pasaran, with neptu • Javanese: day, month, year and taun • Chinese (Imlek): lunar date, zodiac animal and element • Hijri and Gregorian • The moon on every day: phase and how much is lit • Tap any day to read it in every calendar at once, or switch the whole app to the calendar you think in, its own months and years

THREE WAYS TO LOOK • The day, as a tear-off calendar sheet: the date very large, and every calendar's name for it around it • The month, with a dot on every day that has a reminder • The year, twelve months at a glance

A TOOL FOR EACH TRADITION • Bazi (八字): the four pillars of any moment, anywhere, with solar terms worked out to the minute from the sun, true solar time, ten gods, hidden stems, nayin and luck pillars. Where schools disagree you choose, and the chart says whose tables it follows. Nothing you put in is saved unless you write the chart to your journal • Pranata mangsa: the Javanese farming seasons as a wheel through the year • Lintang Jawa: Waluku, Lumbung and the other stars the seasons were read by, on tonight's sky • Prayer times: the five prayers on a 24-hour dial, with a countdown to the next. In Indonesia as the Ministry of Religious Affairs reckons them; elsewhere by the convention your mosque follows • Hilal: the young crescent at sunset after the new moon, weighed against MABIMS, wujudul hilal, Odeh and Yallop. Astronomy only: it never declares a month begun • The ephemeris: where the sun and the moon stand now, through a day, a month or a whole year • The planets: where each stands tonight, the planetary hours of the day, and their old lore • A star map: every star you can see from where you are, tonight or any night, found by name • Light, for photographs: golden and blue hours, where the sun and moon rise and set, the Milky Way, meteor showers and eclipses, the days the sun lines up with a landmark, and a compass set to true north

A JOURNAL KEPT BY DAY • Entries under categories you make, each in its own colour: dreams, observances, occasions, a plant log, anything • Tags for finer sorting • Markdown: bold, italic, lists, headings, footnotes • An optional geotag, rounded to about 100 metres

SEARCH BY ANY CYCLE • Find what you wrote by category, tag or word, or by any cycle of any calendar: every entry on Kliwon, every full moon, every Malam Jumat, every month of Sura • Count the evening as the next day, at sunset or at six, as Javanese and Islamic reckoning do • See what you found as a list, or laid on a month or a whole year, so patterns show

A PRACTICE TIMER • Time a sitting, a fast or a vigil with a stopwatch or a timer, or count by touch, like prayer beads • When it ends, write it into the journal under a category, ready for your notes, or let it go

REMINDERS THAT FOLLOW YOUR CALENDAR • Every weton, pasaran or weekday; the same day each Javanese, Hijri or Chinese month or year; every full moon • Or by the sun: at sunrise, sunset, the golden or blue hour, or a planet's hour, worked out again for every day • They keep coming with the app closed

YOURS, AND ONLY YOURS • No account, no ads, no tracking • Everything stays on your iPhone or iPad as plain Markdown files • Export the whole journal whenever you like • Pick your place by name or on a map, offline, rounded to about 11 km • Optional sync through a GitHub repository you own

ON YOUR IPHONE AND IPAD • Widgets on the lock and home screens, with the day in every calendar and the moon • A practice under way in the Dynamic Island • On the iPad, upright or on its side

A manual in the menu shows every feature on its own screen. Dark and light, upright or on its side. English and Indonesian.

Looks too good to be true? Perhaps. Or perhaps I'm just tired of ads everywhere. No ads, no tracking, nothing sent to me, ever. At least here, you are NOT the product.
