Thursday Auspicious Hours: Which Hours Are Lucky?

Ask when a new venture should begin, and from old craftsmen to today's shopkeepers the most common answer is the same: "Make it a Thursday." In the tradition of auspicious hours (eşref saatleri), Thursday really is the most recommended day of the week. But the real question of this article is subtler: does Thursday open its doors equally wide for everyone? Let us look first at the day's general table, and then at the part that is not the same for all.

Why Is Thursday Seen as the "Day of Beginnings"?

In classical timing lore every day of the week is assigned to a planet, and Thursday's planet is Jupiter (Müşteri). Among the seven classical planets, the tradition calls Jupiter the greater fortune (sa'd-ı ekber) and links it with growth, abundance, good outcomes and protection. That is why Thursday is favoured for planting the seed of a project, putting the first signature on an agreement or setting up a new routine.

Thursday's place in Islamic culture comes from a different source, and the two should not be mixed. In a hadith narrated by al-Tirmidhi, the Prophet said that deeds are presented to God on Mondays and Thursdays, and that he loved for his deeds to be presented while he was fasting. This is why fasting on Mondays and Thursdays is regarded as a sunnah. So Thursday is held in esteem on two levels, a religious one and a traditional timing one; the second is never used as proof for the first.

Thursday's 24 Planetary Hours

In the system of planetary hours, the day starts at sunrise, not at midnight. The span from sunrise to sunset is divided into 12 "day hours", and the span from sunset to the next sunrise into 12 "night hours". Thursday's first day hour belongs to the day's ruler, Jupiter; after that the sequence turns in this order: Saturn, Jupiter, Mars, Sun, Venus, Mercury, Moon, and back to the start.

A closer look at the table reveals a few things:

• Over one full Thursday (day and night), Jupiter takes the stage four times: the 1st and 8th day hours and the 3rd and 10th night hours.
• Venus, which the tradition calls the lesser fortune (sa'd-ı asgar), receives three hours: the 4th and 11th day hours and the 6th night hour.
• Even a fortunate day has its cautious hours: Saturn, the greater malefic (nahs-ı ekber), rules the 7th day hour and the 2nd and 9th night hours; Mars, the lesser malefic (nahs-ı asgar), rules the 2nd and 9th day hours and the 4th and 11th night hours.
• The last hour of the night belongs to the Sun; the next one falls to Venus, so Friday's first hour opens with Friday's own planet. This shows that the sequence is internally consistent.

How Long Is an Hour? A Hypothetical Winter Thursday

A planetary hour is not 60 minutes; it stretches and shrinks with the season and the city. To show this, imagine an entirely hypothetical winter Thursday on which the sun rises at 07:50 and sets at 17:02.

• Daylight lasts 9 hours 12 minutes, or 552 minutes. 552 ÷ 12 = 46 minutes: on that day one day hour lasts 46 minutes.
• The night lasts 1440 − 552 = 888 minutes. 888 ÷ 12 = 74 minutes: this time the night hours are the long ones.
• On this hypothetical day, Jupiter's day hours fall at 07:50–08:36 and 13:12–13:58, and its night hours at 19:30–20:44 and, the next morning, 04:08–05:22.

In your own city the same Thursday will look completely different; these figures only illustrate the logic of the calculation. In summer the picture is reversed: day hours grow longer and night hours shorter.

Thursday Evening, Friday Night

The night column of the table deserves a second look. In planetary hours, Thursday's night runs from Thursday's sunset to Friday's sunrise. In Islamic reckoning, however, a new day begins at sunset, so the night that links Thursday to Friday is called Friday night (laylat al-jumu'a). In short, two traditions give two different names to the same stretch of time.

Among Muslims, Friday night is regarded as a blessed night. Many families have made it a cherished habit to spend it in prayer, sending blessings upon the Prophet (salawat), reading the Qur'an and remembering their departed with mercy. The source of this blessing is the religious texts and the virtue of Friday itself, not planetary hours. The tradition of auspicious hours only adds a language of timing to this night: the fact that the 3rd and 10th hours of Friday night fall to Jupiter is a detail that followers of this tradition find striking.

Mini Q&A: "Is Thursday Lucky for Me, Too?"

Is Thursday equally fortunate for everyone?

The general table is the same for everyone; Jupiter's hours fall in the same order whoever they are calculated for. In the tradition, however, how "open" an hour is to a person is judged by the relationship between the hour's planet and the ruling planet that comes from that person's name. That is why the most recommended day of the week may not be the strongest day of the week for some people.

So is Thursday a bad day for some?

No. Jupiter's general abundance is not considered closed to anyone. What changes is the point of emphasis: for one person Thursday's most productive window is the Jupiter hour, while for another the Venus or Sun hour of the same day may be seen as a better fit.

Should nothing be done in Thursday's Mars and Saturn hours?

The tradition treats these hours as "cautious", not "forbidden". They are not chosen for a new beginning, but there is no need to put life on hold for routine tasks, ongoing follow-ups or commitments planned in advance. Timing does not replace common sense.

Can I find my ruling planet myself?

Your ruling planet is found through a separate calculation based on your name and your mother's name; it does not have to match your sign. We do not give the method here, because a wrong determination leads to misreading even a correct table.

If I miss Thursday, should I postpone my plans?

No. Auspicious hours are a guide for choosing, not an obligation. The other days of the week also have Jupiter hours; Thursday is simply the day this planet rules, the day when its hours are most "concentrated".

A Quick Check Before You Use Thursday

• Find the sunrise and sunset times for that Thursday in your city.
• Divide the daytime and the night-time spans by 12 separately.
• Mark the Jupiter hours (day hours 1 and 8, night hours 3 and 10).
• Separately consider whether your undertaking falls in an hour that suits the ruling planet of your own name; this is the part the general table cannot tell you.

The information in this article introduces the Abjad and auspicious-hours tradition and does not guarantee any outcome. The judgement of planetary hours is not a religious ruling, and many scholars approach such timing practices with caution. A blessed beginning depends above all on intention, prayer, effort and sound decisions.
