1. The axiom: at the time of the וסת, separating one עונה from tashmish alone
The starting point:
Most women have a וסת (a regular cycle: 20/20, 30/30 days…). As the time of the וסת approaches, the husband must separate from his wife for a single עונה (one half-cycle: the day OR the night when the וסת is expected). This perishah applies only to tashmish (marital union) — not to the other signs of affection (חיבוק ונישוק remain permitted, Beit Yossef; one who is stringent, תבוא עליו ברכה). The principle is דרבנן (וסתות דרבנן): which is why, for a mitzvah, it is set aside. The practical consequence: track the וסת (a calendar, a טהרת המשפחה app) and separate in time.
| Concept | What is required | Cross-reference |
|---|
| פרישה (the separation) | One עונה before the וסת, but from tashmish alone | seif 2; Taz s.k. 2 |
| עונה (the half-cycle) | Day OR night, according to the moment of the וסת | seif 2 |
| וסתות דרבנן | A rabbinic presumption → במקום מצוה לא גזרו | PT s.k. 3 (Nodaa BiYehuda) |
💡 The marker: this is not the siman of the harchakot of niddah (siman קצ״ה); here, at the time of the וסת alone, only tashmish is forbidden. Three words to remember: וסת (the cycle), עונה (the half-cycle to separate), פרישה (separating from tashmish alone). And one principle: all of this is דרבנן, which explains the traveler's pekidah and the pregnancy / nursing exemption.
2. The 3 reflex questions
■ WHICH וסת? (קבוע / לא קבוע · בימים / בגוף) — is the וסת קבוע (fixed, established 3×) or לא קבוע? Is it תלוי בימים (tied to a date) or תלוי בשינוי הגוף (tied to a bodily sign, cf. siman קפ״ט)? The perishah of the עונה applies only to the וסת תלוי בימים (Rama, seif 2).
↓ we look at the עונה
■ WHICH עונה? (day or night) — the וסת is expected by day → one separates for the whole day; by night → one separates for the whole night. If it advances or recedes by 2-3 days → one separates those days (seif 2). The woman must also examine herself (bedikah) at the time of the וסת, according to the case (seif 9).
↓ we look at the woman's status
■ PERISHAH OR EXEMPTION? (קטנה / זקנה / מעוברת / מניקה) — only the גדולה is concerned; קטנה, זקנה, מעוברת (after the embryo is recognized) and מניקה (24 months) are exempt from perishah (seif 3, 7). Before a journey, however, the husband פוקד אשתו (seif 10).
⚖ The traveler's pekidah (seif 10 · Taz s.k. 14)
One who sets out on a journey (יוצא לדרך) must פוקד אשתו (be with her) even near the time of the וסת. The Rama: even tashmish is permitted, for וסתות דרבנן ובמקום מצוה לא גזרו; one who is stringent through דברי ריצוי, תבוא עליו ברכה. All קורבה is permitted except tashmish itself; a journey for a mitzvah → not even pekidah (per the views). For the application to your situation, consult your Rav (or a competent Yoetzet).
3. The master grid: וסת קבוע / לא קבוע, the עונה, the perishah, the exemptions
An absolute must to memorize. Basis: Mehaber seifim 1-12, read with the Rama, the Taz (s.k. 2, 10, 14) and the Shach (s.k. 1), via the cross-references to simanim קפ״ט and קצ״ו.
| Element | Decisive criterion | Result |
|---|
| Type of וסת |
קבוע (established 3×) / לא קבוע |
🟡 The קבוע fixes the עונה; the לא קבוע calls for caution (seif 1) |
| Nature of the וסת |
תלוי בימים / תלוי בשינוי הגוף |
🔴 The perishah of the עונה applies only to the תלוי בימים (Rama; קפ״ט) |
| The עונה to separate |
day OR night, according to the moment |
🔴 A single עונה; a shifting וסת → 2-3 days (seif 2) |
| Scope of the perishah |
tashmish alone (חיבוק ונישוק permitted) |
🟢 Only tashmish is forbidden (Beit Yossef; Taz s.k. 3) |
| קטנה / זקנה |
no simanim / blood ceased (3×) |
🟢 No perishah as long as not established (seif 3) |
| מעוברת / מניקה |
embryo recognized / 24 months |
🟢 Exempt from perishah; אין דמים מצויין (seif 7; קפ״ט) |
| The traveler (יוצא לדרך) |
פוקד אשתו, וסתות דרבנן |
🔴 Even tashmish permitted (במקום מצוה לא גזרו) — seif 10 |
| The bedikah at the וסת |
examine when the וסת arrives |
🟡 כל המרבה לבדוק משובחת; י״א forbidden until bedikah (seif 9) |
📌 Key reading: first ask which וסת (קבוע or not; tied to days or to the body), then which עונה to separate (day or night), finally which status (a גדולה bound to perishah, or exempt). And always keep in mind: the perishah touches only tashmish, because everything rests on וסתות דרבנן.
4. The "foundation" box: וסתות דרבנן and the traveler's pekidah
⚖ Why does tashmish become permitted again for the traveler?
All the leniency of the siman flows from one fundamental question: are the וסתות דאורייתא or דרבנן?
- The great מחלוקת: according to the Nodaa BiYehuda (brought in the PT s.k. 3), the וסתות are דרבנן as to the presumption — but the חזקת טהרה remains.
- The נפקא מינה: since it is דרבנן, במקום מצוה לא גזרו — for the mitzvah of the pekidah before a journey (Taz s.k. 14), and to permit חיבוק ונישוק (Taz s.k. 3), the Sages did not decree.
Hence the practice: at the time of the וסת one separates from tashmish for one עונה, but for a mitzvah (the traveler who does pekidah) tashmish becomes permitted again. This is what ties the ordinary perishah (seif 2) to the traveler's pekidah (seif 10) and to the exemptions of the מעוברת / מניקה (seif 7).
5. The 5 golden rules
- פרישה = one עונה, from tashmish alone. At the time of the וסת one separates by day OR by night, and only tashmish is forbidden — חיבוק ונישוק remain permitted (Mehaber seif 2; Taz s.k. 3).
- וסת תלוי בימים, not בגוף. The perishah of the עונה applies only to the וסת tied to days; the וסת tied to a bodily sign is settled at siman קפ״ט (Rama seif 2).
- Exemptions: קטנה, זקנה, מעוברת, מניקה. As long as the וסת is not established 3×, or during pregnancy (embryo recognized) and nursing (24 months), no perishah — אין דמים מצויין (Mehaber seif 3, 7).
- יוצא לדרך → פוקד אשתו. The traveler is with her even near the וסת; וסתות דרבנן ובמקום מצוה לא גזרו → tashmish itself is permitted (Rama seif 10; Taz s.k. 14).
- בדיקה at the time of the וסת. The woman examines herself when the וסת arrives; outside of tashmish, כל המרבה לבדוק הרי זו משובחת (Mehaber seif 1, 9).
6. Mnemonic — the "עונה" memory aid
"ע-ו-נ-ה" — the four moments of the siman
- ע — עונה to separate: a single half-cycle, the day OR the night of the וסת.
- ו — וסת to track: קבוע or לא קבוע, תלוי בימים (not בגוף).
- נ — guarded from tashmish alone: the perishah touches only the union (חיבוק ונישוק permitted).
- ה — going on a journey / pregnancy: the traveler does pekidah (tashmish permitted); pregnancy / nursing exempt.
The exemptions from perishah (seif 3, 7)
- קטנה → no simanim yet / וסת not established 3×
- זקנה → the blood has ceased (3×)
- מעוברת → after the embryo is recognized
- מניקה → 24 months, even if the child died (קפ״ט)
7. The 4 classic pitfalls
❌ Pitfall 1 — Believing the perishah is like the harchakot of niddah: at the time of the וסת, only tashmish (the union) is forbidden. The חיבוק ונישוק and the other signs of affection remain permitted (Beit Yossef; Taz s.k. 3). The harchakot proper belong to niddah itself (siman קצ״ה), not to this siman. For your situation, consult your Rav.
❌ Pitfall 2 — Forgetting the pekidah before a journey: one might think that near the וסת any union is ruled out. Wrong: the יוצא לדרך פוקד אשתו, and even tashmish is permitted, for וסתות דרבנן ובמקום מצוה לא גזרו (Rama seif 10; Taz s.k. 14). It is a mitzvah, not a transgression. For the details, consult your Rav.
❌ Pitfall 3 — Applying the perishah in pregnancy or nursing: after the embryo is recognized (עיבור) and during the 24 months of nursing (מניקה) — even if the child died — there is no perishah near the וסת, for אין דמים מצויין (Mehaber seif 7; cross-reference קפ״ט). Do not impose a stringency the halacha has lifted. For the details of the dates, consult your Rav.
❌ Pitfall 4 — Confusing וסת תלוי בימים and וסת תלוי בגוף: the perishah of the עונה described here applies only to the וסת tied to days (בימים). The וסת tied to a bodily sign (בשינוי הגוף) — sneezes, pains… — follows other rules, set out at siman קפ״ט (Rama seif 2). Do not mechanically apply the counting of days to a bodily וסת.
For the halacha lema'asse, consult your Rav (or a competent Yoetzet).
8. Recap of the 12 seifim — one line each
| Seif | Subject | The essential |
|---|
| 1 | וסת קבוע and the bedikah | Most women have a וסת (20/20, 30/30…). A woman with a וסת קבוע: union outside the time of the וסת without bedikah before tashmish (Rambam). Rama: do not be stringent to examine before/after tashmish ("שלא יהא לבו נוקפו ופורש"); but outside of tashmish, כל המרבה לבדוק הרי זו משובחת. |
| 2 | פרישה one עונה; day / night | At the time of the וסת: separate one עונה, and from tashmish alone (חיבוק ונישוק permitted, מחמיר תע״ב). Day/night mechanics by the moment of the וסת. Rama: only for the וסת תלוי בימים, not בשינוי הגוף (קפ״ט); a וסת that advances/recedes 2-3 days → separate those days. |
| 3 | גדולה only; קטנה / זקנה | The perishah applies only to a גדולה. A קטנה (no נעורים / simanim) or a זקנה (blood ceased): no perishah as long as the וסת is not established 3×. |
| 4 | Daybreak (uncertainty) | If it is unknown whether the וסת was before or after daybreak → one forbids the day alone (out of doubt), per the details of the seif. |
| 5 | A prolonged sighting around daybreak | A sighting that extends around daybreak → one separates the night AND the day, the doubt covering both עונות. |
| 6 | A וסת of 2-3 days (שופעת) | If the וסת lasts 2-3 days (שופעת / מזלפת) → one separates only the first עונה; once it has passed without her seeing → she is permitted. |
| 7 | מעוברת / מניקה: the exemption | עיבור (after the embryo is recognized) / מניקה (24 months, even if the child died): no perishah near the וסת, and even during it she is permitted without bedikah (אין דמים מצויין; cf. קפ״ט). |
| 8 | Hidden out of fear at the וסת | A woman hidden out of fear (war, danger) at the time of the וסת → she need not be concerned. Rama: י״א that this is only bediavad. |
| 9 | The bedikah when the וסת arrives | The other women: bedikah when the וסת arrives; if it passed without bedikah and without הרגשה → טהורה without bedikah. י״א: forbidden until she examines if it is a וסת קבוע or yom 30 (והכי נהוג; cf. קפ״ט). |
| 10 | היוצא לדרך → פוקד אשתו | One who sets out on a journey must פוקד אשתו even near the וסת. Rama: even tashmish permitted (וסתות דרבנן, במקום מצוה לא גזרו); stringent with דברי ריצוי תע״ב; all קורבה permitted except tashmish; a journey for a mitzvah → no pekidah; י״א if she is nidda and immerses within the עונה, wait. |
| 11 | וסת לימים: ישאלנה | וסת לימים: at the time of the וסת, forbidden until he consults her (ישאלנה); no וסת → yom 30 is its equivalent; if enough time has passed to count and she immersed → permitted without asking. |
| 12 | וסת לימים + תלוי בגוף (קפיצה) | A וסת לימים joined to a וסת תלוי בגוף (קפיצה): like one tied to an action ("אימור לא קפצה"), yet she is concerned for the עונה בינונית = 30 days (cf. קפ״ט). |
9. Final flashcard
| Question | Reflex answer | Source |
|---|
| How much to separate at the time of the וסת? | A single עונה (day OR night) | Mehaber seif 2 |
| What does the perishah forbid? | Tashmish alone (חיבוק ונישוק permitted) | Beit Yossef; Taz s.k. 3 |
| Which וסת calls for this perishah? | The וסת תלוי בימים, not בגוף (קפ״ט) | Rama seif 2 |
| Who is exempt from perishah? | קטנה, זקנה, מעוברת, מניקה (24 months) | Mehaber seif 3, 7 |
| And one who sets out on a journey? | פוקד אשתו; even tashmish permitted | Rama seif 10; Taz s.k. 14 |
| Why this leniency? | וסתות דרבנן; במקום מצוה לא גזרו | PT s.k. 3 (Nodaa BiYehuda) |
| Is a bedikah needed at the time of the וסת? | Yes, per the case; כל המרבה לבדוק משובחת | Mehaber seif 1, 9 |
| A וסת that advances/recedes? | Separate the 2-3 days concerned | Rama seif 2 |
⚖ The reflex in 3 questions
- Which וסת, which עונה? קבוע or not, תלוי בימים (not בגוף); one separates a single עונה, day OR night.
- Perishah or exemption? From tashmish alone (חיבוק ונישוק permitted); קטנה, זקנה, מעוברת, מניקה are exempt.
- And the journey? The traveler does pekidah, even tashmish permitted (וסתות דרבנן, במקום מצוה לא גזרו).
For the application to your situation, consult your Rav (or a competent Yoetzet).

💡 Suggested next steps:
- Re-read Siman קפ״ד in the original Choulhan Aroukh (Hebrew) with the Shach, the Taz and the Pitchei Teshuva
- Study the adjacent simanim: 183 (the foundation of niddah), 189 (the laws of וסתות — the central siman), 190 (the כתמים), 195 (the harchakot of niddah), 196 (the שבעה נקיים and the בדיקות)
- Delve into the מחלוקת וסתות דרבנן / דאורייתא and the logic of the presumptions (חזקת טהרה)
- For personal cases (tracking the וסת, a journey, pregnancy, nursing) — the halacha le-ma'aseh is decided with a Rav (or a competent Yoetzet)
