2506: Thai Months Oct 22, 2021

In modern Thai, months with 30 days end in '-ayon' and months with 31 end in '-akhom'; February (Kumphaphan) ends in '-phan'. Originally in Thai, the months were just numbered, but later these were Thai-modified Sanskrit named introduced by prince Devawongse Varoprakar based on the Zodiac signs, with both endings mentioned above meaning 'arrival'. This makes something like October 'tulakhom' from 'tulā' (balance) meaning 'the arrival of balance' from 'Libra', or April as 'Mesayan' from 'mesa' (ram) from Aries and so on. The different ending for February means 'bound', and the added day of a leap-year is called 'Athikasuratin' meaning 'additional'.
