Technically, one should wear Tefillin all day. We don't, since we can't keep ourselves clean the whole day.

But we still put it on once a day during Shacharis, since we can presumably keep ourselves clean for such a short period of time.

But lets say one didn't put on Tefillin by Shacharis. Say one was sick, or forgot them at home, or wasn't allowed to due to Tisha BeAv.

The Halacha is one should put them on sometime during the day (or Mincha). Why?

What's the source for our current practice that "one should not let a day go by without wearing Tefillin"?

The fact that a biblical exegesis - Drasha, is needed to exempt the obligation to wear teffilin on Yom Tov and Shabbos, implies that when it is not either shabbos or Yom tov, there is an obligation to wear them every day.

Rav Yitzchok Yosef in his Kitzur Shulchan Aruch (אות ג') presents this very argument:

אף ששלא נתבאר בפירוש בתורה שצריך להניח בכל יום ויום, מכל מקום מדמצינו פטור מהנחת תפילין לגבי שבת ויו''ט, משמע דבשאר ימים יש חובה להניחן. שהרי נאמר בתורה (שמות לא, יג): אך את שבתותי תשמרו כי אות היא ביני וביניכם. וגבי מילה נאמר בבראשית (יז, יא): והיה לאות ברית ביני וביניכם. וגבי תפילין נאמר בשמות (יג, ט) והיה לך לאות על ידך. ואמרו בעירובין (צו.) ר''ע אומר יכול יניח אדם תפילין בשבתות וימים טובים ת''ל והיה לך לאות על ידך מי שצריכין אות, יצאו אלו שהן גופן אות. ובמנחות (לו:) תנא, ושמרת את החוקה הזאת למועדה מימים ימימה, ימים ולא לילות, מימים ולא כל ימים פרט לשבתות וימים טובים, דברי ר' יוסי הגלילי, ר''ע אומר לא נאמרה חוקה זאת אלא לענין פסח בלבד. ומפרש בגמ' דקסבר ר''ע דלילה זמן תפילין, ושבתות וימים טובים לאו זמן תפילין. וע' בקידושין (לג:). וכ''פ מרן בש''ע (סי' כט, וסי' לא) דאין מניחין תפילין בשבת וביו''ט. וכ''ה בהקדמת תיקוני הזוהר (דף ג'). ומכאן יש ללמוד שחייבים להניח תפילין בכל יום, ומן התורה הוא חיוב מתמשך ותמידי משנעשה לאיש, ואינו מתחדש בכל יום, מלבד שבתות ימים טובים וחול המועד. ומה שאין מניחין תפילין בלילה הוא מדרבנן גזרה שמא יפיח בהם. והיינו כשיכול לא להסיח דעתו מהם. [ילקו''י תפילין במבוא להלכות תפילין. ובמהדורת תשס''ו עמוד רפח]


Although there is no explicit source that there is an obligation to wear Teffilin everyday, nonetheless from the fact that one is exempt from Shabbos and Yamim Tovim implies that there is an obligation to wear them everyday.


Rav Moshe Sternbuch in Teshuvos Vehanhagos (חלק ב' סימן ל') quotes in the name of the Brisker Rav that teffilin is not a new mitzvah everyday single day, rather it is a constant mitzvah.

  • I don't understand this argument at all? From this it seems you have to put it on once per week (maybe?). Where did every day come from? He says explicitly that Layla Zman Tefillin.

Tosafos in Shabbos 131 seems to hold that a Mitzva which is incumbent upon us constantly must be done at least every day.

  • +1 He seems to say it must be done once per obligatory period. Tzitzis is each day (night time you are exempt), but Tefillin would be each week (only Shabbat you are exempt). no?

  • @DoubleAA What about Succos and Mezuza? Actually, Tosafos is referring to the Shita that the night garment is not excluded.

Pri Megadim (Eshel Avraham 37:2) discusses whether there is a daily obligation.

Rabbeinu Yonah (Iggeres Teshuva Ois 24) writes that one who doesn’t wear tefillin has close to 300 עונשים yearly (excluding Shabbos and Yom Tov etc.), which sounds like one transgresses the commandment for each day one doesn't wear Tefillin.

The Gemara (Menachos 44) writes “he who doesn’t fulfill the obligation of tefillin transgresses eight commandments”. Smag (Asei #3) and Shibolei HaLeket (Inyan Tefillin) are clear that one transgresses these eight commandments daily.

(See Tosfos [Menachos 35b], where a disagreement is presented as to whether one must tie the tefillin daily.)

The Brisker Rav — quoted by Reb Moshe Shternbuch תשובות והנהגות ח”א סי’ מ”ט, ח”ב סי’ ל, ח”ג סי’ י”א — held that the obligation is all day, and that there is nothing different about today than tomorrow. Therefore, not wearing it for a whole day does not constitute a greater deal of bitul (nullification of the commandment) than not wearing it for an hour. See also Moadim Vezmanim.
