Must
You mustn't do something = необходимо, чтобы вы не делали этого (нельзя этого делать) |
You don't have to do something = вы не обязаны этого делать (но вы можете, если хотите)
|

- Вместо needn't, вы можете употребить don't/doesn't need to. Так, вы можете сказать:

- I didn't need to ... = для меня нет необходимости ... (и я знаю это):
- I didn't need to get up early, I stayed in bed till 10.
- I needn't have done something = я сделал это, но теперь я знаю, что в этом не было необходимости:
- I got up very early because I had to get ready to interview. But in fact it didn't take me long to get ready. So, I needn't have got up so early. I could have stayed in bed longer.
