Thanks for the suggestion, Tom. I searched for the topic in Chrome community but found nothing. I tried one more thing before posting the question. I managed to partially change the Dutch to English in the calendar. This time the settings menu was in English, so I was able to read it. I changed the primary region and language and time zone accordingly, when suddenly the language partially changed to Bangla. Not even sure what I did, but I eventually got rid of the Bangla. I restarted my computer and it was fixed. I do not even know which step it was that did the trick. If the problem recurs, I just need to remember that the first option under the settings menu is settings. One click on that gets you to the page to change region, etc.
