What is the difference between these phrases?
now and then
now and again
Google says that they mean the same. So saying “Every now and then I go for trekking” is same as “Every now and again I go for trekking”, right? If not then what would be proper use case for each of these?
The proper use case for each is the same, so use whichever you prefer, however you should correct the latter half of the sentence, removing the word ‘for’:
Now and then I go trekking.
