+# Format And Print The Current Date And Time
+
+If I run the `date` command from the terminal, I get output like the following:
+
+```bash
+$ date
+Fri Jan 22 13:45:44 CST 2021
+```
+
+If I want to format the date output different, perhaps for inclusion in a shell
+script, I can do something like this:
+
+```bash
+$ date +"%Y/%m/%d %H:%M:%S"
+2021/01/22 13:47:55
+```
+
+Then I can incorporate that in a script like this:
+
+```bash
+now() {
+  echo "Today: $(date +'%Y/%m/%d %H:%M:%S')"
+}
+```
+
+This
+[page](https://www.tutorialkart.com/bash-shell-scripting/bash-date-format-options-examples/)
+includes some examples and a page of formatting options.
