Most of the big bus operators had similar systems. Bournemouth, for
instance, had a service lane in the garage into at least the '80s, and
the last digit of the fleet number matched the service rota day, so
every bus got a safety check every ten days,

... except in February.

And all those double checks on 31st's followed by a 1st. Perhaps they
had a cunning scheme for these eventualities?
