Is it realistic that mountain cultures use a different calendar than the low landers?

My fantasy setting is on a wet and humid world of innumerable islands; many of which are quite mountainous.

With conditions ranging from Mediterranean to Tropical.

The culture here experience only two seasons Wet/Rainy and Dry. Their Calendar divides the year into two seasons.

Which in turn divides each season into three phase of Waxing, Apex and Waning, the beginning, middle and end of the season; each phase divides into months.

With mountain regions often being cooler than the low lands in reality.

I thought that the Mountain folk might experience different season, and develop a more earth like Calendar?

If the above/bolded not plausible then what would be?

• Would the Mountain folk use the same Calendar system as the low landers?
• Would the Mountain Folk experience a different enough condition from the low landers and most real worlds cultures to need a unique Calendar?
• If the immediately above is true, what are mountain seasons and weather like?
