Google crawls your site anytime, if you index your page or provide new content so we cannot say how and when. It can anytime crawl.

Google's spiders regularly crawl the web to rebuild our index. Crawls are based on many factors such as PageRank, links to a page, and crawling constraints such as the number of parameters in a URL. Any number of factors can affect the crawl frequency of individual sites. crawl process is algorithmic; computer programs determine which sites to crawl, how often, and how many pages to fetch from each site. We don't accept payment to crawl a site more frequently. For tips on maintaining a crawler-friendly website
Google crawl daily on quality site. Google crawling is depend upon usability of the website and PR of the website. If your site having 5 and more PR then google crawl your site every day.
It depends on how frequently you update your website. If Google get updates from your website regularly through blog update or any other content update in website, it crawl your website regularly.
Thank you so much all of you. Your all comments are very informative and nice. Actually I want to know let suppose i have a site and i want to know how many times google crawl this website in one month or previous month? Then how can i check it? Thank you so much once again.
depends on your site....certain sites get crawled daily, some weekly, others every few hours. We have our site getting crawled several times during the day. It depends on what the crawlers learn about your website. If they notice fresh and new content being added several times during the day, the crawlers learn to visit more frequently.
As has been mentioned, the primary factor in the crawl rate is how often new content is added. One one of my forums, the content is constantly changing and I get 2-3 crawls per day; on busier forums (and ones with higher PageRank and better SERPs) the rate can be as little as minutes.
Google robots will crawl your site when ever you update it with content, The way I do it is I update my blogs every week at the same time, this way google expects my sites to be update and crawls them right away.
