Думаю, разумным будет вести двойной счёт лет:

от Рождества: #РХ2025
от Сотворения: #зфл҃д
и, опционально, #MMXXV

Тэгаем текущий год:

#2025 — числительные не тэгаются
#MMXXV — с римскими числами никаких проблем
#҂вк҃є — знак «тысяча» не проходит, можно #вк҃є, но тут не совсем корректно: 2-25
#βκε — с греческим та же проблема
