The table above brings today's Subha Hora (Planetary Hours), Yama periods such as Rahu Kala, Yamaganda, and Gulika, and Muhurtha timings together in one view for your selected city. Use the 'Options' (โฎ) menu to choose the timings you want to see, and turn on Sub-Hora to view the finer divisions within each planetary hour. Each row shows the start and end time, the ruling planet where applicable, and whether the period is generally considered favourable for new beginnings. Timings are calculated using the exact local sunrise and sunset for your location. Select 'Use current location' (๐ฆ) to get timings for your precise position, and the table will update automatically. Since each hora is one-twelfth of the actual daylight or night, its length changes with the season, latitude, and daylight hours rather than following a fixed 60-minute clock.
What is Subha Hora?
Subha Hora (also written shubha hora, shubha horai, or simply planetary hours) is a Vedic timekeeping method that divides each day and night into twelve equal parts. The Sanskrit word hora comes from ahoratra (เค เคนเฅเคฐเคพเคคเฅเคฐ), meaning the full cycle of day and night. Half of ahoratra gives hora - and this is the same root from which the English word hour derives. In everyday Hindu practice, a shubha hora is an auspicious planetary hour: a window when the ruling graha's qualities are considered supportive for the activity at hand. The table on this page shows all twenty-four hora for the date and city you selected, so you can see which interval is active now and plan accordingly.
How the 24 Hora are calculated
Calculation begins at local sunrise. The first hora of the day is always ruled by the planet that governs the weekday - the Sun on Sunday, the Moon on Monday, Mars on Tuesday, Mercury on Wednesday, Jupiter on Thursday, Venus on Friday, and Saturn on Saturday. Each following hora advances through the Chaldean sequence: Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon, then back to Saturn. This pattern repeats through all twelve day hora until sunset, and again through twelve night hora until the next sunrise. Because day and night are each split into twelve equal spans, a hora near midsummer lasts longer than one in midwinter at the same location. Boundaries here use your city's astronomical sunrise and sunset, so they reflect real daylight rather than a uniform clock hour.
The seven Hora and what each favours
Each of the seven classical planets lends a distinct tone to its hora. Choosing an interval whose character matches your task is the practical heart of Subha Hora. The summaries below describe traditional associations used across much of South Asian Jyotish; local custom may vary.
Surya (Sun)
The Sun hora is authoritative, visible, and leadership-oriented. It suits government filings, public announcements, meetings with senior figures, health-related appointments, and honouring one's father or elders. Sunday naturally strengthens this hora; Saturday, ruled by Saturn, is traditionally considered less supportive for Sun-ruled work. Ruby is the gemstone linked to Surya in classical texts.
Chandra (Moon)
The Moon hora is receptive, emotional, and changeable. Travel, domestic arrangements, care for mothers or children, meditation, and water-related activities are commonly placed here. Monday amplifies lunar themes. Tuesday's martial tone is often treated as less comfortable for Moon-ruled tasks. Pearl is the traditional gemstone of Chandra.
Mangal (Mars)
Mars brings energy, courage, and decisive action. Physical exercise, competitive sport, property matters, engineering work, and situations requiring firm boundaries fit this hora. Tuesday is Mars's own day. Friday's Venusian softness is traditionally viewed as a weaker match for Martian work. Red coral is associated with Mangal.
Budha (Mercury)
Mercury governs intellect, speech, commerce, and detail. Writing, trading, accounting, short journeys, study, and negotiations are well suited to a Budha hora. Wednesday strengthens Mercury's influence. Thursday's Jupiterian breadth is sometimes considered less precise for Mercury's quick, analytical tasks. Emerald is Mercury's classical gemstone.
Shukra (Venus)
Venus hora favours harmony, beauty, and connection. Marriage discussions, artistic work, music, decoration, romance, and luxury purchases are traditional choices. Friday is Venus's day. Sunday's solar assertiveness is often treated as less aligned with Venusian ease. Diamond (or white sapphire in some traditions) is linked to Shukra.
Guru (Jupiter)
Jupiter is expansive, wise, and dharmic. Teaching, religious ceremonies, legal consultations, charitable giving, and long-term planning belong here. Thursday is Jupiter's own weekday. Wednesday's Mercurial speed is sometimes seen as less ideal for Jupiter's measured, principled work. Yellow sapphire is Guru's traditional gemstone.
Shani (Saturn)
Saturn hora emphasises discipline, patience, and structure. Hard labour, agricultural work, iron or stone crafts, settling debts, and sustained effort without hurry are appropriate. Saturday belongs to Shani. Sunday's solar brilliance is traditionally considered a weaker backdrop for Saturn's slow, methodical tone. Blue sapphire is associated with Shani in many lineages.
Subha Hora vs Choghadiya vs Gowri Panchangam
These three tools all divide the day into auspicious segments, but they answer different questions. Subha Hora assigns each interval to one of the seven planets in Chaldean order from sunrise - useful when you want to match an activity to planetary character. Subha Choghadiya uses a separate eight-fold day/night scheme with labels such as Amrit and Labh; it is widely used in North and West India for quick good/bad windows. Gowri Panchangam is the Tamil Nadu variant of the same choghadiya family, often consulted alongside Nalla Neram. Use the hora table when planetary theme matters; use choghadiya or Gowri when you need a simple auspicious/inauspicious label for a fixed activity type.
Nalla Neram and regional names
In Tamil Nadu and among Tamil-speaking communities worldwide, auspicious daily windows are often called Nalla Neram (good time) or Shubha Horai - horai being the Tamil form of hora. A priest, calendar publisher, or family elder may refer to the same planetary-hour sequence you see here under a regional name. Those labels describe the same underlying calculation: twelve day and twelve night divisions from local sunrise, ruled in Chaldean order from the weekday lord.
How these timings are computed
Subha Hora is calculated with the Swiss Ephemeris for precise solar positions, Lahiri ayanamsa for sidereal conventions used in Indian panchangam, and your city's geographic coordinates for local sunrise and sunset. Daylight-saving transitions are handled through the IANA timezone database, so a hora boundary in New York or London shifts correctly when clocks change. The result is a location-accurate hora table you can trust for today's date without manual lookup in a printed panchangam.
