+## Commits between `m` and `n` days ago (date ranges)
+
+You can also combine the `-u`/`-A` and `-d`/`-B` flags to select a range of days, including a range of a single day:
+- The value of `-u` must always be less than or equal to the value of `-d`.
+- The value of `-A` must always be sooner than or equal to the value of `-B`.
+- Using `-u`/`-A` by itself without `-d`/`-B` will give you zero results.
+
+For example, if today is Monday 2020-05-16 and you want a log for the previous Friday 2020-05-15 (3 days ago), you can use:
+
+```shell
+# Saturday was 2 days ago, Friday was 3 days ago
+# Using -u and -d means "between 2 days ago and 3 days ago"
+# Shows commits for Friday
+git standup -u 2 -d 3
+
+# Only using -d means "between now and 3 days ago"
+# Shows commits for Friday, Saturday, and Sunday
+git standup -d 3
+
+# Same results as above
+git standup -u 0 -d 3
+
+# This also works with the -A and -B flags
+
+# Between Friday 2020-05-15 and Saturday 2020-05-16
+git standup -A "2020-05-15" -B "2020-05-16"
+
+# Between today and 2020-05-16
+git standup -B "2020-05-16"
+
+# Same result as above
+git standup -A "2020-05-18" -B "2020-05-16"
