Well, since it is "The Land Before Time", I don't think these guys even knew what a calendar is

. The only example I could think of is in LBT VII when Pterano is sentenced to five cold times. A cold time happens every year, so maybe that was their way of keeping track of years at least

. Stardays too, though I'm sure how they kept track of those :huh:.
I wonder though...where in the heck did Ichy learn about July

? Same place he found those mystery binoculars

?
