Rahu Kalam, Yamagandam, Kuligai Timings, Complete Vedic Inauspicious Periods Guide
Hindu daily astrology identifies three significant inauspicious time windows: Rahu Kalam, Yamagandam, and Kuligai. Each is approximately 90 minutes long (one-eighth of daylight hours), each is governed by a different planetary influence, and each is traditionally avoided for starting new ventures. Together, they account for roughly 4.5 hours of daily time that classical Hindu astrology recommends avoiding for major life decisions. This article covers all three windows, how to calculate them, and how they apply at Tirumala for pilgrimage planning.
The three inauspicious time windows
| Window | Governed by | Avoid for |
|---|---|---|
| Rahu Kalam | Rahu (shadow planet) | New ventures, signings, journeys, ceremonies |
| Yamagandam | Yama (death-related, son of Surya) | Same as Rahu Kalam |
| Kuligai (Gulika Kalam) | Gulika (son of Saturn) | Same as Rahu Kalam |
How they’re calculated
All three are calculated identically:
- Find local sunrise and sunset times
- Calculate daytime duration
- Divide by 8, this is the segment length
- The day of the week determines which segment number is the relevant window
For a typical 6:00 AM to 6:00 PM day, each segment is 90 minutes.
Day-of-week to segment mapping
| Day | Rahu Kalam (segment) | Yamagandam (segment) | Kuligai (segment) |
|---|---|---|---|
| Sunday | 8th | 4th | 6th |
| Monday | 2nd | 3rd | 5th |
| Tuesday | 7th | 2nd | 4th |
| Wednesday | 5th | 1st | 3rd |
| Thursday | 6th | 5th | 2nd |
| Friday | 4th | 6th | 1st |
| Saturday | 3rd | 7th | 8th |
(Segment 1 is the first 1/8 of the day starting at sunrise; segment 8 is the last.)
Approximate clock times (6 AM sunrise)
| Day | Rahu Kalam | Yamagandam | Kuligai |
|---|---|---|---|
| Sunday | 4:30 PM – 6:00 PM | 10:30 AM – 12:00 PM | 1:30 PM – 3:00 PM |
| Monday | 7:30 AM – 9:00 AM | 9:00 AM – 10:30 AM | 12:00 PM – 1:30 PM |
| Tuesday | 3:00 PM – 4:30 PM | 7:30 AM – 9:00 AM | 10:30 AM – 12:00 PM |
| Wednesday | 12:00 PM – 1:30 PM | 6:00 AM – 7:30 AM | 9:00 AM – 10:30 AM |
| Thursday | 1:30 PM – 3:00 PM | 12:00 PM – 1:30 PM | 7:30 AM – 9:00 AM |
| Friday | 10:30 AM – 12:00 PM | 1:30 PM – 3:00 PM | 6:00 AM – 7:30 AM |
| Saturday | 9:00 AM – 10:30 AM | 3:00 PM – 4:30 PM | 4:30 PM – 6:00 PM |
Actual times vary by city based on sunrise / sunset. Equatorial cities (Chennai, Bengaluru) have smaller variation; northern cities (Delhi) have wider seasonal swing.
What to avoid during these windows
- Starting new business ventures
- Signing important contracts
- Marriage ceremonies / wedding muhurtam
- Beginning religious / spiritual practices for the first time
- Major financial decisions
- Auspicious housewarming (Griha Pravesha)
- Long journeys (especially for religious purposes)
What you CAN do during these windows
- Continue ongoing work and routine activities
- Pray to specific deities, Rahu remedies, Yama mantras, Saturn mantras
- Recite Hanuman Chalisa (protective)
- Visit specific remedy temples, Sri Kalahasti (Rahu remedies)
- Donate to charities
- Meditate, read scripture
Tirumala pilgrimage planning
For Tirumala specifically:
- TTD does not formally suspend any temple activity during these windows
- The temple’s daily ritual cycle runs continuously
- However, pilgrims often choose to avoid these windows for:
- Booking a Kalyana Vedika wedding
- Beginning a vow / mokku
- Tonsuring (head-shaving as vow fulfilment)
- Major donation pledges
For darshan itself, the temple’s ritual cycle is considered to override personal Rahu Kalam concerns, many devotees pursue darshan during these windows without modification.
The combined avoidance
Strict observers avoid all three windows combined, approximately 4.5 hours per day. Practical observers focus on Rahu Kalam (most widely cited) and only worry about Yamagandam / Kuligai for the most consequential decisions.
Common questions
Are these windows the same on every same day-of-week? The segment number is fixed (Tuesday = 7th for Rahu Kalam etc.). The absolute clock time shifts with seasonal sunrise/sunset changes.
Should I delay my Tirumala visit for these windows? The temple operates 24/7. Most devotees do not modify their pilgrimage schedule for these windows. For specific high-stakes ceremonies (wedding, major donation), do consider.
What about night windows? Classical calculation covers daytime only. Some sources extend to nighttime with separate calculations; not widely observed in practice.
What about Sri Kalahasti’s Rahu-Ketu Pooja? Sri Kalahasti’s specific Rahu remedy is performed regardless of Rahu Kalam timing, the pooja itself is the remedy.
