The tithi on 18 June 2026 is Shukla Paksha Chaturthi. A tithi is one lunar day — the time the Moon takes to move 12° further from the Sun — and it governs which observances, fasts and ceremonies suit the day. End times on this page are converted to Buffalo Grove local time (America/Chicago).
The Moon is in Ashlesha nakshatra. The zodiac is divided into 27 nakshatras of 13°20′ each; the one the Moon occupies colours the day's character and matters for naming ceremonies, travel decisions and muhurat selection in Buffalo Grove.
Today's yoga is Vyaghata. Yoga is computed from the combined longitudes of the Sun and Moon and cycles through 27 names; some yogas are read as favourable for new undertakings while others counsel routine work.
On 18 June 2026 the sun rises in Buffalo Grove at 5:15 AM and sets at 8:30 PM. Sunrise is the hinge of the whole panchang: the Hindu day begins at local sunrise, and Rahu Kalam, Yamaganda, Gulika and the choghadiya sequence are all equal divisions of the daylight between these two moments.
The five limbs of the panchang — tithi, nakshatra, yoga, karana and vara — have guided Hindu timekeeping for millennia, and this page works all five out specifically for Buffalo Grove, Illinois. On 18 June 2026 the day unfolds under the Shukla Paksha Chaturthi tithi with the Moon in Ashlesha nakshatra. Because the timings are tied to Buffalo Grove's own horizon (42.15°N, 87.96°W), they differ from the figures an Indian city would show.
The reason a generic almanac misleads is geometry. Buffalo Grove stands at 42.15°N, 87.96°W and runs on America/Chicago time, so the Sun crosses its horizon on a schedule unlike any Indian city's. On 18 June 2026 the sun rises over Buffalo Grove at 5:15 AM and sets at 8:30 PM — figures no Indian city shares — and Rahu Kalam, Yamaganda, Gulika, the eight choghadiya periods and Abhijit Muhurat are each cut from the interval between this local sunrise and sunset. Use IST figures in Buffalo Grove and every window lands at the wrong moment — and over a wide enough longitude gap, the date's tithi itself can change.
Behind the timings on this page is a precise pipeline: Swiss Ephemeris longitudes for the Sun and Moon, adjusted by the Lahiri (Chitrapaksha) ayanamsa adopted in India's Rashtriya Panchang. The rule is simple — a tithi closes when the Moon is 12° further along than the Sun, a nakshatra when the Moon enters the next 13°20′ span. Those moments hold worldwide, so we translate each into America/Chicago time and then compute Rahu Kalam, the choghadiya and the rest from Buffalo Grove's actual sunrise and sunset. See our methodology page for the full working.
For the Hindu community in Buffalo Grove and the wider Illinois area, this page answers the practical questions: when to schedule a puja, griha pravesh, vehicle purchase, mundan or journey on Thursday, 18 June 2026. Abhijit Muhurat (12:22 PM – 1:23 PM) is the day's most dependable auspicious window, while Rahu Kalam (2:47 PM – 4:41 PM) is best avoided for new beginnings. For longer ceremonies, pick a favourable choghadiya from the tables above — all in Buffalo Grove local time, so what you read is what your clock shows.
A panchang is the Hindu almanac that describes each day through five limbs — tithi (lunar day), nakshatra (the Moon's constellation), yoga, karana and vara (weekday) — and from them derives the day's auspicious (muhurat) and inauspicious (Rahu Kalam, Yamaganda) periods. This page computes all of them for Buffalo Grove, United States.
The daylight between Buffalo Grove's local sunrise and sunset is divided into eight equal parts, and one fixed part belongs to Rahu depending on the weekday (for example the 8th part on Sunday, the 2nd on Monday). Because Buffalo Grove's sunrise and day length differ from India's, its Rahu Kalam falls at different clock times than in Indian cities.
Rahu Kalam in Buffalo Grove on 18 June 2026 is from 2:47 PM – 4:41 PM Illinois local time. It is computed from Buffalo Grove's own sunrise and sunset — not India's — so it differs from Rahu Kalam in Indian cities.
The tithi is Shukla Paksha Chaturthi, until 8:31 AM local time. Tithi end times are converted to Buffalo Grove's timezone (America/Chicago).
All panchang timings depend on local sunrise and sunset. Buffalo Grove (42.15°, -87.96°) has different sun times than India, so Rahu Kalam, choghadiya and muhurat windows shift — and because of the time difference, even the tithi prevailing on your calendar date can differ from India's. This page is computed specifically for Buffalo Grove.
Abhijit Muhurat, the most auspicious window of the day, is 12:22 PM – 1:23 PM local time in Buffalo Grove.
