We donโ€™t say โ€œhan byouโ€, โ€œhan funโ€, or โ€œhan jikanโ€ by putting โ€œhanโ€ before.
For โ€œdayโ€ and longer durations, โ€œhanโ€ can come before the number.

  • ๅŠๆ—ฅ๏ผˆใฏใ‚“ใซใก๏ผ‰ (han nichi - half day)
  • ๅŠๆœˆ๏ผˆใฏใ‚“ใคใ๏ผ‰ (han tsuki - half month)
  • ๅŠๅนด๏ผˆใฏใ‚“ใจใ—๏ผ‰ (han toshi - half year)

However, be careful of the pronunciation:

  • ร—ใฏใ‚“ใ’ใค (han getsu - incorrect for half month)
  • ร—ใฏใ‚“ใญใ‚“ (han nen - incorrect for half year)

We often use โ€œhan nichiโ€, โ€œhan tsukiโ€, and โ€œhan toshiโ€ for approximate halves.
If you want to say exactly half, use โ€œjyuu ni jikanโ€, โ€œjyuu go nichiโ€, or โ€œroku kagetsuโ€.

Others

Notes:

  • There is a clear distinction between โ€œ2ๆ™‚ (2 oโ€™clock)โ€ and โ€œ2ๆ™‚้–“ (2 hours).โ€
  • For other units like โ€œ็ง’ (second),โ€ โ€œๅˆ† (minute),โ€ โ€œๆ—ฅ (day),โ€ โ€œๆœˆ (month),โ€ and โ€œๅนด (year),โ€ you can use ้–“ (kan) or not to express duration.
  • This applies when expressing duration, not for the current time.
  • Examples:
    • โ€œ1็ง’โ€ or โ€œ1็ง’้–“โ€ (one second)
    • โ€œ5ๅˆ†โ€ or โ€œ5ๅˆ†้–“โ€ (five minutes)
    • โ€œ2ๆ—ฅโ€ or โ€œ2ๆ—ฅ้–“โ€ (two days)
    • โ€œ2ใƒถๆœˆโ€ or โ€œ2ใƒถๆœˆ้–“โ€ (two months)
    • โ€œ1ๅนดโ€ or โ€œ1ๅนด้–“โ€ (one year)
  • Both are acceptable and mean the same thing.
    • โ€œ15ๅˆ†ๅพ…ใฃใฆไธ‹ใ•ใ„โ€ or โ€œ15ๅˆ†้–“ๅพ…ใฃใฆไธ‹ใ•ใ„โ€ (Please wait 15 minutes.)
    • โ€œ3ๅนดๅ‹‰ๅผทใ—ใพใ—ใŸโ€ or โ€œ3ๅนด้–“ๅ‹‰ๅผทใ—ใพใ—ใŸโ€ (I studied for 3 years.)
  • In conversation, ้–“ is often omitted.
