Okay time for the time lore!
It is currently the Seventh Astral Era as of the end of the 2.0 storyline. After each era changes, the years reset. The most recent Calamity ended the Sixth Astral Era and brought on the Seventh Umbral Era. Five years later, the leaders of the grand companies officially declared the Umbral Era ended and the 1st year of the Seventh Astral Era began.
More lore:
-Units of Time & Eras Lore
-Time Bubble
If you're wanting a birth date for your 19 year old, they'd be born in the Year 1558 of the Sixth Astral Era.
Hope this helps!
