Summary of Everyday English: Time, Family, and Routines

## Introduction Telling time is a fundamental skill for communication, organization, and academic life. In this material, we'll cover how to express time in English and Spanish (with an emphasis on Spanish), how to read analog and digital clocks, and how to use common expressions like "quarter past," "half past," "to," and "past." You'll learn to convert between formats and to use time in real-world contexts such as class schedules and appointments. > Definition: Time is the measure that indicates the relative position of the hour and minute hands on a clock. It is expressed in 12-hour and 24-hour formats. ## Basic Concepts ### Time Formats - 12-hour clock: uses AM and PM to distinguish morning from afternoon/evening. - 24-hour clock: runs from $00:00$ to $23:59$ and is common in official systems (transportation, university schedules). > Definition: AM (ante meridiem) and PM (post meridiem) indicate before and after midday, respectively. Comparison Table: 12-hour vs 24-hour format | 12-hour Format | 12-hour Example | 24-hour Format | 24-hour Example | |----------------|-----------------|----------------|-----------------| | 7:30 AM | seven thirty AM | $07:30$ | $07:30$ | | 3:20 PM | three twenty PM | $15:20$ | $15:20$ | | 12:45 PM | twelve forty-five PM | $12:45$ | $12:45$ | ### Reading an Analog Clock - The short hand indicates the **hour**; the long hand indicates the **minutes**. - Each number represents 5 minutes on the clock face: $1=5$ min, $2=10$ min, ..., $12=60$ min. ### Common English Expressions and their Spanish Equivalents - "o'clock" = "en punto" → 8:00 = "eight o'clock" = "las ocho en punto". - "half past" = "y media" → 5:30 = "half past five" = "las cinco y media". - "quarter past" = "y cuarto" → 10:15 = "quarter past ten" = "las diez y cuarto". - "quarter to" = "menos cuarto" / "faltan cuarto" → 1:45 = "quarter to two" = "las dos menos cuarto". - "Past" indicates minutes after the hour; "to" indicates minutes before the next hour. > Definition: "Past" is used for minutes after the hour (e.g., "twenty past nine" = 9:20). "To" is used for minutes before the next hour (e.g., "ten to twelve" = 11:50). ## Practical Examples with Explanations (Solved Exercises) 1) Write the time in sentences (examples from the original material): - 2:30 → "It’s two thirty" or "It’s half past two". - 8:00 → "It’s eight o’clock". - 10:15 → "It’s ten fifteen" or, more commonly, "It’s quarter past ten". - 12:45 → "It’s twelve forty-five" or "It’s quarter to one". - 9:25 → "It’s nine twenty-five" or "It’s twenty-five past nine". - 3:20 → "It’s three twenty" or "It’s twenty past three". - 3:40 → "It’s three forty" or "It’s twenty to four". - 5:05 → "It’s five oh five" or "It’s five past five". - 11:50 → "It’s eleven fifty" or "It’s ten to twelve". 2) Matching Exercise (Practice for Completion): - A - Quarter to two → $1:45$ → "one forty-five". - B - Five past ten → $10:05$ → "ten oh five". - C - Twenty-five to four → $3:35$ → "three thirty-five". - D - Ten to one → $12:50$ → "twelve fifty". - E - Twenty past seven → $7:20$ → "seven twenty". - F - Twenty to three → $2:40$ → "two forty". - G - Five to twelve → $11:55$ → "eleven fifty-five". - H - Quarter past eight → $8:15$ → "eight fifteen". - I - Ten past nine → $9:10$ → "nine ten". - J - Half past five → $5:30$ → "five thirty". - K - Twenty-five past six → $6:25$ → "six twenty-five". - L - Eleven o'clock → $11:00$ → "eleven o’clock". Did you know that many languages use relative expressions (like "quarter to") instead of counting exact minutes, because they make quick conversation and remembering schedules easier? ## Converting Between Formats (24-Hour Practice) - To convert PM times to 24-hour format (for hours from 1 PM to 11:59 PM), add 12 to the hour: $2\!:\!30\text{ PM} \to 14\!:\!30$. - Examples: - $8\!:\!00\text{ AM} = 08\!:\!00$. - $3\!:\!20\text{ PM} = 15\!:\!20$. - $12\!:\!45\text{ PM} = 12\!:\!45$.
