Add days to new month

[ghost]

It would be handy to know when the new month starts as there is no indicator as to when that may be.

To avoid congesting the UI with more information, it would likely be best shown in the requests tooltip.

In favour of readability, my preferred way of viewing it would be similarly to the first example below: "In 8 days, on 9 January, you'll get another 5GB".
Or in AGDNS's case: "In 31 days, on 1 February, you will get another 10M requests".

Here are some examples from apps that I use.
