Comparing last modified dates

Hi All.

Can someone please give me an example of how I'd do a comparison to find out if the last modified date of a file is newer than yesterday (i.e. today - 1 day)?

Example:

if [ last modified date of text.txt -ge yesterday]; then
echo "Do something..."
fi

Any ideas or examples?

Thanks.
