+# Date Filters
+The exporter currently supports three date filters, namely, between, before, and after. All date filters are inclusive.
+
+## Format
+The option takes keywords to identify the type and therefore the format must be followed:
+
+* Between filter keyword: ` - `, and the format is `<date> - <date>`
+* Before filter keyword: `< `, and the format is `< <date>`
+* After filter keyword: `> `, and the format is `> <date>`
+
+## Date Format
+The default date format is `%Y-%m-%d %H:%M`. You can change it with the `--range-format` option. The value should be a formatting string supported by `strftime` and `strptime` functions.
+
+For example, if you want to supply an ISO compliant date: `wtsexporter -a --range "< 2024-01-01T00:00:00.00000Z" --range-format "%Y-%m-%dT%H:%M:%S.%fZ"`
+
+## Example
+### Between
+This will export messages received or sent between 2023-01-01 00:00 to 2024-01-01 00:00, inclusively.
+```
+wtsexporter.exe -a --range "2023-01-01 00:00 - 2024-01-01 00:00"
+```
+
+### Before
+This will only export messages received or sent before 2024-01-01 00:00.
+```
+wtsexporter.exe -a --range "< 2024-01-01 00:00"
+```
+
+### After
+This will only export messages received or sent after 2023-01-01 00:00.
+```
+wtsexporter.exe -a --range "> 2023-01-01 00:00"
+```
