Dates anywhere in the text quoted can be tagged with precision using the <date> element:

         He succeeded his father                   <persName ref="PRS8550sardaDe"><roleName type="title">ʾaṣe</roleName>
            Śarḍa Dǝngǝl</persName> when he was 15 years old in <date>1597</date>. 

Example 1

<date calendar="ethiopian" when="1888" when-custom="1881" evidence="internal">፲ወ፰፻፹ወ፩ ዓመት፡ ምሕረት፡ </date>

Example 2

@when always carries the standard ISO date in the Gregorian calendar, while the @when-custom (or @notBefore-custom, @notAfter-custom) can hold the value in the calendar specified by @calendar.

BCE dates are therefore expressed with -: <death when="-0931">

date expressing a duration rather than a point in time, might use the @dur following w3c recommendations. A period of 10 years and 5 months would be encoded as

<date dur="P10Y5M"></date>
