Prepositions of Time — In, On, At
Hindi में/को/पर don't split time the way English does
Category: Prepositions
The Rule
'At' for specific times (at 3 PM). 'On' for days/dates (on Monday, on July 4th). 'In' for longer periods (in January, in 2024, in the morning). Hindi uses को or में for most.
Why This Matters
Hindi: 'सोमवार को' (Monday को), 'जनवरी में' (January में), '3 बजे' (3 o'clock — no postposition). English: on Monday, in January, at 3. The three-way split doesn't exist in Hindi.
Examples
• The meeting is at 10 AM. — "मीटिंग सुबह 10 बजे है।" ['At' for clock times] • I was born on March 15th. — "मेरा जन्म 15 मार्च को हुआ।" ['On' for specific dates] • It gets cold in December. — "दिसम्बर में ठंड होती है।" ['In' for months/seasons/years]
Common Mistakes
❌ I wake up on 7 AM. ✅ I wake up at 7 AM. → Clock times use 'at', not 'on'. 'On' is for days. ❌ The exam is at Monday. ✅ The exam is on Monday. → Days of the week use 'on', not 'at'.
Quick Tip
AT = exact time (at noon, at 5 PM). ON = specific day (on Tuesday, on Dec 25). IN = a period (in winter, in 2024, in the afternoon).
