Adverbials of time

We use adverbials of time to say:

when something happened:

She was born in 1978.
I will see you later.
There was a storm during the night.

• for how long :

We waited all day.
They have lived here since 2004.
We will be on holiday from July 1st until August 3rd.

how often (frequency):

They usually watched television in the evening.
We sometimes went to work by car.

We often use a noun phrase as a time adverbial:


yesterday last week/month/year one day/week/month last Saturday
tomorrow next week/month/year the day after tomorrow next Friday
today this week/month/year the day before yesterday the other day/week/month

the exercise was nice..:)

Would U please help
Are these sentences grammatically well formed?
Up until then I thought I was very clever, but......
Before that time I had not seen him . 

Yes, both of those sentences are well formed. It's more common to say something like 'I hadn't seen him before then' and 'Up till then I thought I was very clever', but there's nothing wrong with your sentences.
