A longitudinal study
First confirmed ice cream van sighting of 2022 occurred at 11:55 on March 26th. The van, Raja’s Ices, was heading south along Kingswood Road, playing Teddy Bears' Picnic.
This year’s Saturday observation further establishes the weekend as the most likely time of the week see that first ice cream van. Saturday and Sunday together account for more observations than Monday to Friday combined. The time, 11:55, is the earliest in the day yet recorded, with most sightings occurring between 16:00 and 17:15. The date is within expectation.
The full ice cream van data is available as a spreadsheet.
Projecting from data gathered thus far, we project that next year’s first ice cream van should appear on the afternoon of 9th March 2023, with an envelope of +5/-2 days.
