grep for a current date in a particular format

This is RHEL 5 os. I'm using bsh.
I am trying to grep a log for the current date.
The way the log records the date is in this format:
02/Apr/2015:11:38:44

How do I grep for the current day and month? The rest of the date doesn't matter.

So far this is my command:
grep page.jsp /path_to_log/access.log | grep 404

Id like to include only to search for todays date as I dont care about past dates.

Thanks in advance.

Assuming that /path_to_log/access.log is the name and path of the logfile:

grep ^$(date "+%d/%b/")  /path_to_log/access.log

The above works only if the date starts at position 1 of the respective line. If it doesn't omit the caret:

grep $(date "+%d/%b/")  /path_to_log/access.log

Thanks for the response but that doesn't seem to work. I still get all dates, not just today's date.

So try

grep ^`date "+%d/%b/"` /path_to_log/access.log

If there is no date of todays date in file then you should have seen no output at all.

Please try the above "backtick" version, if needed without the caret.
