 The existing base Odoo two-week calendar functionality is hidden rather than
 disabled. This may or may not be desirable.
+
+The module may need improvements for timezone handling; this is currently
+untested. ``_split_into_weeks`` splits weeks on the timezone of the datetime
+objects passed to it instead of on the timezone of the calendar. The calculation
+of the current week number uses ``fields.Date.today()`` instead of the
+environment's or calendar's timezone. Finally, child calendars may have a
+different timezone compared to their parent, which is probably not a desired
+feature.
+
+This module assumes that a week always starts on a Monday. Upstream Odoo appears
+to do the same, but this may not be desired by certain audiences.
