Taiwan (XTAI) missing trading day 2024-09-16

[dinohsu1019]

Taiwan calendar (XTAI) should be updated, since 2024-09-16 is a trading day, version 4.5.6, thanks.

Code:
import pandas as pd
import exchange_calendars as xcals
xtai = xcals.get_calendar("XTAI") # Taiwan stock exchange
all_xtai_trade_dates = list(xtai.schedule.index.values)
print(xcals.version)
list(filter(lambda x: pd.Timestamp('2024-09-01') <= x <= pd.Timestamp('2024-09-30'), all_xtai_trade_dates))

Output:
4.5.6

Faced this same issue. I think it has to do with the Mid autumn timings for Taiwan.
