From https://dictionary.cambridge.org/pronunciation/english/today it looks like it's like

  today -> too-deh-I

where the last "I" is like the "i" in "ship" and not like the "ee" in "sheep". I agree that it's not a very strong "ee" sound.

I see /təˈdeɪ/ on that page. Per their https://dictionary.cambridge.org/help/phonetics.html page, the eɪ is how they encode what the other site uses ā for. That is, the "ɪ" is not a separate syllable from the "e".

I pronounce them in the same syllable, but I used an incorrect notation.
