Koj puas tau tsis meej pem thaum lub moos qhia tus lej zoo li 14.24? Yog tias yog, nws txhais tau tias koj tsis paub nrog 24-teev kev sau ntawv. Daim ntawv ntawm kev nthuav qhia no feem ntau siv hauv kev ua tub rog ntawm Tebchaws Meskas, Europe, thiab lwm lub tebchaws hauv ntiaj teb. Hmoov zoo, hloov 24-teev hom rau 12-teev (tus qauv) thiab rov ua dua yog yooj yim heev ua. Tsuas yog nco ntsoov tias koj tsuas yog yuav tsum tau hloov cov teev, thaum cov feeb tseem zoo ib yam.

Txoj Kev 1 ntawm 2: Hloov 24-Teev Sijhawm Rau 12-Teev
Kauj Ruam 1. Ntxiv 12 rau thawj teev ntawm hnub thiab muab "AM" thaum kawg
Hauv 24-teev hom ntawv, ib tag hmo sau raws li 00.00. Yog li, thawj teev txij li ib tag hmo, sau 12 thiab tus cim "AM" los hloov nws mus rau hom ntawv 12 teev. Piv txwv li, 00.13 hauv 24-teev hom ntawv yog 12.13 AM hauv hom ntawv 12 teev.
Koj puas paub?
Cov ntawv luv "AM" thiab "PM" yog keeb kwm Latin. "AM" sawv rau "ante meridiem" uas txhais tau tias "ua ntej tav su" thaum PM sawv rau "post meridiem" uas txhais tau tias "tom qab tav su."
Kauj Ruam 2. Kos “AM” rau lub sijhawm ntawm 1.00 txog 11.59
Txij li hom ntawv 24-teev txav los ntawm 00.00 (ib tag hmo) mus rau 1.00, koj tsuas yog xav tau ntxiv tus cim "AM" rau lub sijhawm los ntawm 1.00 txog 11.59. Koj tseem tuaj yeem tshem tus lej zeros, piv txwv li 06.28 hauv 24-teev hom ntawv yog 6.28 AM hauv 12-teev hom. Nws txhais tau tias:
- 01.00 = 1.00 Nws
- 02.00 = 2.00 Nws
- 03.00 = 3.00 Nws
- 04.00 = 4.00 Nws
- 05.00 = 5.00 Nws
- 06.00 = 6.00 Nws
- 07.00 = 7.00 Nws
- 08.00 = 8.00 Nws
- 09.00 = 9.00 Nws
- 10.00 = 10.00 Nws
- 11.00 = 11.00 Nws
Kauj Ruam 3. Kos “PM” rau 12.00 txog 12.59
Rau ib teev tom qab 12 teev tsaus ntuj, sau yooj yim "PM" kawg kom hloov 24-teev hom ntawv mus rau 12-teev. Piv txwv li, 12.45 dhau los ua 12.45 PM.
Kauj Ruam 4. Txiav 12 rau lub sijhawm txij thaum 13:00 txog 23:59, thiab suav nrog "PM"
Rau lub sijhawm tom qab 13:00, hloov 24-teev hom ntawv mus rau 12 teev los ntawm kev rho tawm 12. Tom qab ntawd, muab "PM" thaum kawg. Piv txwv li, yog tias koj xav hloov 14.36 rau 12-teev hom, rho tawm 12 kom tau 2.36, tom qab ntawd nkag mus rau "PM". Koj tsis tas yuav sau zeros ua ntej teev teev hauv 12 teev. Yog li ntawd:
- 13.00 = 13.00 Nws
- 14.00 = 14.00 Nws
- 15.00 = 15.00 Nws
- 16.00 = 16.00 Nws
- 17.00 = 17.00 Nws
- 18.00 = 18.00 Nws
- 19.00 = 19.00 Nws
- 20.00 = 20.00 Nws
- 21.00 = 21.00 Nws
- 22.00 = 22.00 Nws
- 23.00 = 23.00 Nws
Txoj Kev 2 ntawm 2: Hloov Cov Qauv 12 Teev rau 24 Teev Sijhawm
Kauj Ruam 1. Siv 00.00 los qhia ib tag hmo hauv 24-teev hom ntawv
Hloov chaw ntawm kev siv "12.00" ob zaug hauv 24-teev lub sijhawm zoo li hom 12-teev, hom ntawv 24-teev siv "00.00" los qhia ib tag hmo. Qhov no txhais tau tias koj tsuas yog yuav tsum sau cov feeb. Piv txwv li, 12.30 AM ua 00.30.
Koj puas paub?
Tsis muaj 24.00 hauv 24-teev hom vim tias tom qab 23.00 (11.00 teev tsaus ntuj) yog 00.00 (12.00 teev sawv ntxov).
Kauj Ruam 2. Tshem “AM” rau teev nruab nrab ntawm 1.00 thiab 11.59 AM
Hloov lub moos ntawm ib tag hmo thiab nruab hnub nrig los ntawm hom 12 teev mus rau 24 teev yog qhov yooj yim heev. Tsuas yog xav tau tshem tus cim "AM". Yog tias teev tus lej yog ib tus lej, muab tus xoom tso rau ntawm nws xub ntiag. Yog li, piv txwv li, 6.00 AM yog 06.00 thiab 10.15 AM yog 10.15. Yog li ntawd:
- 1.00 AM = 01.00 Nws
- 2.00 AM = 02.00 Nws
- 3.00 AM = 03.00 Nws
- 4.00 AM = 04.00 Nws
- 5.00 AM = 05.00 Nws
- 6.00 AM = 06.00 Nws
- 7.00 AM = 07.00 Nws
- 8.00 AM = 08.00 Nws
- 9.00 AM = 09.00 Nws
- 10.00 AM = 10.00 Nws
- 11.00 AM = 11.00 Nws
Kauj Ruam 3. Tawm lub sijhawm nruab hnub raws li nws yog, tshem tawm "PM
"Koj tsis tas yuav hloov dab tsi los ntawm 12.00 teev tsaus ntuj txog 12.00 hauv 24-teev hom ntawv, tshwj tsis yog tshem tawm" PM "tag. Yog li, piv txwv li thaum 12:22 teev tsaus ntuj nws yuav yog 12:22.
Kauj Ruam 4. Ntxiv 12 rau lub sijhawm nruab nrab ntawm 1.00 txog 11.59 PM thiab tshem "PM"
Rau nruab hnub, hmo ntuj, yav tsaus ntuj, thiab hmo ntuj, yooj yim ntxiv 12 mus rau 12-teev hom los hloov nws mus rau 24-teev hom. Tsis tas li, tshem "PM". Ntawd yog, 2.57 PM dhau los ua 14.57 thiab 11.02 ua 23.02. Yog li ntawd:
- 1.00 PM = 13.00 Nws
- 14.00 TS 2. = 14.00
- 15.00 TS = = 15.00
- 4.00 PM = 16.00 Nws
- 5.00 PM = 17.00 Nws
- 18.00 TS = = 18.00
- 19.00 TS = = 19.00
- 8.00 TS = = 20.00
- 21.00 TS 9 = 21.00
- 10.00 TS = = 22.00
- 11.00 TS = = 23.00
Lub tswv yim
- Nco ntsoov tias "16.35" raug nyeem ua "kaum rau peb caug-tsib" lossis "peb caug-tsib feeb dhau los kaum rau."
- Feem ntau qhov xoom nyob rau pem hauv ntej ntawm ib tus lej teev tsis tau hais txog. Yog li, piv txwv li, 08:00 yog hu ua "yim yim xoom" lossis yooj yim "yim teev". Rau ib tag hmo (00.00), nws feem ntau tsuas yog "xoom xoom moos".
- Yog tias tsis muaj txoj hnyuv nyob rau teev, tsuas yog muab "teev" thaum pib los qhia txog hom 24-teev. Piv txwv li, hais "1600" raws li "kaum rau teev."
- Vajtswv ua tau vim nws yog ib txwm! Yog tias koj muaj lub cuab yeej digital, tej zaum yuav muaj kev xaiv hloov lub sijhawm tso tawm los ntawm 12-teev hom mus rau 24-teev hom los pab koj siv tau los nyeem lub sijhawm.
- Lwm txoj hauv kev yooj yim thiab nrawm los hloov ob hom ntawv no yog rho 2 los ntawm tus lej thib ob thiab 1 los ntawm thawj tus lej rau teev dhau 12 (piv txwv: 17.00 - 2 = 5.00 PM; 22.00 - 2 = 10.00 PM). Yog tias qhov txiaj ntsig ntawm kev rho tawm yog tus lej tsis zoo, koj yuav tsum rho qhov sib txawv los ntawm qhov txiaj ntsig kawg yog tias koj siv xoom tsis txhob siv qhov tsis zoo (hmoov zoo, qhov no tsuas yog tshwm sim hauv ob kis, 20.00 lossis 8.00 teev tsaus ntuj thiab 21.00 lossis 9.00 teev tsaus ntuj).).
