Telling time
1. TELLING TIME
Telling time is important for practical daily conversation. Here is the first of several Hints
on telling time in English.
TELLING TIME IN ENGLISH: HOURS
There are several common ways of telling the time when it is an hour (and no minutes):
What time is it?
It's 3:00. / It's three.
It's 3 o'clock.
It's 3 A.M. / It's 3 P.M.
It's exactly 3 o'clock.
It's exactly 3 A.M. (P.M.)
It's 3 (o'clock / A.M. / P.M.) on the dot.
It's 3 (o'clock / A.M. / P.M.) sharp.
It's three in the morning / in the afternoon.
It's 5:00. / It's five.
It's 5 o'clock.
It's 5 A.M. / It's 5 P.M.
It's exactly 5 o'clock.
It's exactly 5 A.M. (P.M.)
It's 5 (o'clock / A.M. / P.M.) on the dot.
It's 5 (o'clock / A.M. / P.M.) sharp.
It's five in the morning / in the afternoon.
It's 8:00. / It's eight.
It's 8 o'clock.
It's 8 A.M. / It's 8 P.M.
It's exactly 8 o'clock.
It's exactly 8 A.M. (P.M.)
It's 8 (o'clock / A.M. / P.M.) on the dot.
It's 8 (o'clock / A.M. / P.M.) sharp.
It's eight in the morning / in the evening.
It's 11:00. / It's eleven.
It's 11 o'clock.
It's 11 A.M. / It's 11 P.M.
It's exactly 11 o'clock.
It's exactly 11 A.M. (P.M.)
It's 11 (o'clock / A.M. / P.M.) on the dot.
It's 11 (o'clock / A.M. / P.M.) sharp.
It's eleven in the morning / at night.
2. SPECIAL NOTES:
A.M. is an abbreviation for the Latin ante meridiem (before noon). A.M. is used for times
between midnight and noon--or morning.
P.M. is an abbreviation for the Latin post meridiem (after noon). A.M. is used for times
between noon and midnight--or afternoon, evening, and night.
Noon is 12:00 during the day. Midnight is 12:00 at night.
TELLING TIME IN ENGLISH: MINUTES 1-9
There are several common ways of telling the time when it is an hour and
minutes, and when the minutes are 1-9:
It's (hour):01 / :02 / :03 / :04 / :05 / :06 / :07 / :08 / :09
It's one / two / three / (etc.) after (hour).
It's one / two / three / (etc.) past (hour).
3. It's (hour):51 / :52 / :53 / etc.
It's one / two / three / (etc.) before (hour).
It's one / two / three / (etc.) until (hour).
It's one / two / three / (etc.) 'til (hour).
It's one / two / three / (etc.) to (hour).
SPECIAL NOTES:
1. The minutes after an hour from 1 to 9
(:01, :02, etc.) are usually read oh one,
oh two, oh three, etc.
2. For minutes before an hour, some people
say of instead of before, until, 'til, or to.
3. You can, of course, say exactly or on
the dot with minutes from 1 to 9 (either
before or after an hour) and you can
also say A.M. or P.M.
TELLING TIME IN ENGLISH:
QUARTER HOURS AND HALF HOURS
A quarter hour (1/4 of an hour) is 15 minutes, a half hour (1/2 of an
hour) is 30 minutes, and three quarters of an hour (3/4 of an hour) is 45
minutes.
There are special expressions for time given in quarter hours and half hours:
4. What Time is It?
It's 2:15.
It's a quarter after 2.
It's a quarter past 2.
It's 15 minutes past 2.
It's 15 past 2.
It's 15 minutes after 2.
It's 15 after 2.
It's 2:30
It's half past two.
It's 2:45
It's a quarter before 3. /
It's a quarter until 3. /
It's a quarter 'til 3. /
It's a quarter to 3. /
It's a quarter of 3.
It's 15 minutes before / until / 'til / to / of 3.
It's 15 before / until / 'til / to / of 3.
5. SPECIAL NOTES:
1. In English, at the half hour (2:30, 9:30,
11:30, etc.), we do not say "half + the
next hour" or "thirty before (etc.)
the next hour or "half before (etc.) the
next hour":
wrong: 5:30 = *half six / *thirty
before (etc.) six / *half before (etc.) six
right: 5:30 = half past five or five-thirty
2. In English, at 15 minutes before an
hour (2:45, 7:30, 10:45, etc.), we do
not say "15 minus (or less) the next hour":
wrong: 7:45 = *eight less 15 or *eight
minus 15
right: 7:45 = seven forty-five or
a quarter / fifteen (minutes) before /
until / 'til / to / of eight
