+               'Day': (seconds / 86400) % 7,
+               'Hour': (seconds / 3600) % 24,
+               'Minute': (seconds / 60) % 60,
+               'Second': (seconds % 60)
+              }
+-%}
+
+{% for item in map if map[item] | int > 0 -%}
+  {%- if loop.first %}{% elif loop.last %}, and {% else %}, {% endif -%}
