Most Vedic apps show the same Rahu Kaal for all of India — calculated from a generic IST formula. But Rahu Kaal is 1/8th of the actual daytime from today's sunrise at your location. Kolkata (88.4°E) is India's easternmost major city — sunrise is 24 min earlier than IST meridian, and 62 min earlier than Mumbai. The largest within-India Rahu Kaal gap is Kolkata vs Mumbai. CosmosPandit uses precision astronomy (Jean Meeus, Astronomical Algorithms) to calculate the exact sunrise at Kolkata's coordinates (22.572600°N, 88.363900°E), giving you the correct Rahu Kaal every day.
Kolkata is home to India's most revered Shakti temple — the Kalighat Kali Mandir — and the famous Dakshineswar Kali temple on the Hooghly River, made sacred by Sri Ramakrishna Paramahamsa. As India's easternmost major city at 88.4°E, Kolkata has the earliest sunrise of all major Indian cities — up to 1 hour 18 minutes before Mumbai. Every Rahu Kaal calculation uses Kolkata's precise coordinates, giving exact timings for this uniquely early-sunrise city.
ભારત 30° રેખાંશ જેટલા વિસ્તારમાં એક જ સમય ઝોન (IST, UTC+5:30) વાપરે છે. પણ સૂર્યોદય ઘડિયાળ નહીં, સૂર્ય ને અનુસરે છે — દરેક 1° = 4 મિનિટ ફર્ક. આ રીતે કોલકાતા ના સૂર્યોદય મુંબઈ કરતા 80 મિનિટ વહેલો થાય છે.
આ રાહુ કાળ પેઝ તો બસ શરૂઆત છે. CosmosPandit App દરેક ભારતીય ને તેમની ભાષા અને શહેર ના ચોક્કસ સમય સાથે સંપૂર્ણ ટૂલ્સ આપે છે:
Because Kolkata is at 88.4°E — the easternmost major Indian city. Earth rotates west to east, so eastern cities see the sun first. Each degree of longitude = 4 minutes. Kolkata is 15.5 degrees east of Mumbai, making its sunrise 62 minutes earlier. Rahu Kaal, starting from sunrise, is therefore 62 minutes earlier in Kolkata than Mumbai on the same IST calendar day.
Yes — Howrah (22.59°N, 88.31°E) is directly across the Hooghly from Kolkata and the coordinates are nearly identical. The Rahu Kaal difference is under 1 minute.
Yes. CosmosPandit supports Bengali (বাংলা) — all timings, daily Rashifal, and the full Panchang are available in Bengali. Download the app and select Bengali from language settings.
