All my kiddos are dressed to walk out my laneway to take my kids to the bus. So since they are already all bundled this is when we have our outdoor time. We stay out from 30-60 mins depending on how well they are entertaining themselves. Mind you I have all 2.5-3 year olds right now. This way I don't have to get them dressed a second time and don't go out when it is the end of the day (darker and colder). The rest of the year we stay out in the morning and end our day outside as well.
