Kāla: Lunar & Solar Calendar

One sky, every calendar.

Kāla places the moon back into your calendar. A familiar solar month grid carries a true rendered moon phase on every day, and one tap projects a different calendar system onto the same month: Hindu Panchāngam, astronomical moon phases, Chinese lunisolar, Islamic Hijri, Julian, ancient Roman, or Mayan.

A COMPLETE PANCHĀNGAM
All five limbs, computed from the real positions of the sun and moon: tithi, nakshatra, yoga, karana and vāra, with end times solved to the minute, plus māsa (including adhika māsa), samvatsara, Śaka and Kali years. Choose Amānta or Purnimānta reckoning. Daily muhūrtas too: Abhijit, Rahu Kalam, Yamaganda and Gulika, computed from your actual sunrise and sunset.

NEVER MISS A KEY DAY
Pūrnima, Amāvāsya, Ekādashi, Sankrānti and major festivals are flagged right in the grid, with optional 7 AM alerts. Home screen and lock screen widgets keep today's tithi and moon a glance away.

SEVEN CALENDARS, ONE GRID
The Gregorian month never changes shape; lens chips re-annotate every day in the system you choose. See today as a Hijri date, a Julian date, the Roman Kalends reckoning, or the Mayan Long Count, Tzolk'in and Haab'.

IN YOUR LANGUAGE
Switch languages inside the app, live: Telugu, Hindi, Marathi, Tamil, Kannada, Malayalam, Bengali, Assamese, Gujarati, Punjabi, Odia, Nepali, Sinhala, Urdu, Chinese (Simplified and Traditional), Japanese, Korean, Thai, Vietnamese, Indonesian, Malay, Arabic, Persian, Turkish, Russian, Spanish, French, German and Portuguese. Indic languages show panchāngam names in their own script; right-to-left languages mirror the whole app.

FOR EXACTLY WHERE YOU ARE
Allow location once and every timing is computed for your coordinates and shown in your timezone. Prefer a fixed city? Choose from presets. Everything works fully offline.

THREE MOODS
Cosmic Night, a deep-space theme with luminous phases. Apple Minimal, a system look that disappears into the OS. Traditional Panchāngam, warm vermilion and turmeric like the printed family calendar.
