It usually takes one week. If you are impatient, I advise you to try the Search Console. By copy and paste the URL directly on the website, the Google will be notified to do it quicker, so it may take 3-4 days.
The least important pages seem to get crawled every month or two, and that doesn't seem to have changed much for a long time. The one exception I know of is that Yandex, last I looked, crawls Russian pages once every 5 days, minimum.
