Numbers not being translated

I am making a bilingual site. All numbers stay in Arabic numerals, even for translated pages. My language has its own set of symbols that I sure can use when making the ..md pages. But numerals in dates remain the same. I would like them to be in the other language’s script for all purposes and uses.

Is there any feature in Hugo that I may have missed? I did look around in the documentation and asked ChatGPT. I also use i18n for basic translations in the UI stuff. Is there something I can do in i18n directly, other than using static strings for dates instead of timestamps like ‘2025-07-17T13:31:02+05:30’?

No. Hugo’s localization features include:

You might consider creating a partial that handles this, using something like this as a starting point:
