What is the Samjae Calculator?
The Samjae Calculator is a free tool that takes a single input — your birth year — and works out your Chinese zodiac sign and samhap (三合) group to tell you whether this year falls in your samjae, Korea's traditional three-year caution cycle. If you are in samjae, it shows which of the three stages you are in — entering (deul), settled (nul), or departing (nal) — with a traditional reading for that stage. If you are not, it shows when your next samjae begins.
The result screen includes a timeline that spans from your last samjae to your next one at a glance, a year-by-year table listing the year, its sexagenary name, and its stage, and the three zodiac signs that share your group. The calculation follows the traditional samhap rules exactly, so the answer is the same whenever you check, and you can copy the result link to share with family and friends.
What Samjae Means, Where It Comes From, and How to Face It
The word samjae (三災) is said to come from a Buddhist term for three calamities — water, fire, and wind. In Korean folk cosmology, the twelve zodiac signs are bound into four groups of three (the samhap trines), and each group is believed to pass through this energy for three years out of every twelve — a stretch traditionally treated as a time to be extra careful in all things.
The three years are named by their order: the first is deul-samjae (samjae entering), the second nul-samjae (samjae settled, also called muk-samjae), and the third nal-samjae (samjae departing). The timing is fixed by group: Monkey, Rat, and Dragon signs meet samjae in Tiger, Rabbit, and Dragon years; Snake, Rooster, and Ox signs in Pig, Rat, and Ox years; Tiger, Horse, and Dog signs in Monkey, Rooster, and Dog years; and Pig, Rabbit, and Sheep signs in Snake, Horse, and Sheep years.
What tradition actually prescribes is not a special ritual but everyday diligence: read contracts and documents carefully, keep up ordinary preparations like health check-ups and savings, and never rush a major decision. Samjae is a cultural belief, not a scientific fact — so use it as an occasion for self-review rather than a reason for fear.
Key Features
Automatic Sign, Group, and Stage Detection
From one birth year, the tool computes your zodiac sign and samhap group, then determines whether this year is in your samjae and which stage it is. The traditional rules are implemented exactly, so the result never varies.
Last-to-Next Samjae Timeline
A single timeline shows the flow from your previous samjae to your next one, with a marker for where you stand today — so you can see at a glance when samjae comes and goes.
Three-Year Samjae Table
A year-by-year table lays out the samjae period with each year's sexagenary name and stage — entering, settled, or departing — plus whether it has passed, is this year, or lies ahead.

When to Use It
At the Start of a New Year
Check early in the year whether your sign is in samjae and at which stage, and set the tone for the year ahead. It pairs well with a New Year fortune reading.
Checking the Whole Family
Enter your parents', siblings', and children's birth years one by one to map out the family's samjae periods. You will also see that signs in the same trine share the very same three years.
Before a Big Decision
Consult the traditional view as one reference before a move, job change, or new venture. Samjae never means give up — read it as a signal to prepare more thoroughly.
When Samjae Rituals Come Up
If someone brings up paid samjae rituals, check your actual period and stage here first. Accurate information is the best guard against needless worry or spending.
Frequently Asked Questions
What is samjae (三災)?
Samjae is a Korean folk belief that each of the four zodiac trines — groups of three signs — passes through a cautionary period lasting three years out of every twelve. The word is said to derive from a Buddhist term for three calamities of water, fire, and wind, and in folk life it settled into a piece of practical wisdom: be extra careful during these three years. It is not a scientifically grounded prediction, so treat it lightly, as a prompt for self-review.
When does my sign's samjae fall?
It is fixed by trine. Monkey, Rat, and Dragon signs meet samjae in Tiger, Rabbit, and Dragon years; Snake, Rooster, and Ox signs in Pig, Rat, and Ox years; Tiger, Horse, and Dog signs in Monkey, Rooster, and Dog years; and Pig, Rabbit, and Sheep signs in Snake, Horse, and Sheep years. Enter your birth year in this calculator and it works out your group and dates automatically.
What is the difference between deul, nul, and nal samjae?
They are simply the names of the three years in order. The first year, deul-samjae, is when samjae enters and change begins; the second, nul-samjae (also muk-samjae), is when it settles in and complacency is the thing to watch; and the third, nal-samjae, is when it departs — a year suited to wrapping up and putting things in order. Tradition advised a different mindset for each stage.
What is bok-samjae (福三災), the 'lucky samjae'?
Not every samjae is read as unlucky. In traditional fortune reading, if the flow of those three years happens to work in your favor, samjae can become a springboard instead — this is called bok-samjae, the fortunate samjae. Plenty of people experience promotions, exam passes, or weddings during samjae. The accurate way to understand samjae is not as a prophecy that something bad will happen, but as a signal to be a little more careful than usual.
Which signs are in samjae from 2025 to 2027?
The years 2025 (Eulsa, Year of the Snake), 2026 (Byeongo, Year of the Horse), and 2027 (Jeongmi, Year of the Sheep) correspond to Snake, Horse, and Sheep years — the samjae period of the Hae-Myo-Mi group, meaning people born under the Pig, Rabbit, and Sheep signs. 2025 is the entering year, 2026 the settled year, and 2027 the departing year. From 2028 to 2030, the samjae of the Tiger, Horse, and Dog signs follows.
Should I avoid marriage or moving during samjae?
No. Samjae is a traditional idea meant to encourage carefulness, not a statistic or a science, and far more people marry, move, and start businesses without incident during samjae than not. Even tradition's core message is closer to 'prepare more thoroughly than usual' than 'do not do it'. Treating it as a reminder to double-check schedules and contract terms is entirely sufficient.
Do I need a samjae ritual (samjae-puri)?
It is not required. There was a folk custom of holding a simple samjae ritual in the first lunar month, but its essence was a personal resolution to spend the year carefully. Be wary of commercial schemes that demand large fees or stoke anxiety. In a modern sense, booking a health check-up and reviewing your insurance and contracts is the real samjae-puri.
I was born in January or February — how should I check?
This calculator assigns zodiac signs by calendar birth year. In traditional practice, however, the year is considered to change at Ipchun (the start of spring, around February 4), so people born in January or early February are sometimes counted under the previous year's sign. If that may apply to you, also try your birth year minus one and compare the two results.
