approximately 12th century) cannot be recorded in the 046 field.
<span style="color:red>'''Repeatability:'''</span>
<span style="color:red>Field 046 is repeatable, but the 046 subfields used to record the dates are not repeatable. Generally, one 046 field with dates conforming to the EDTF schema should be sufficient. However, century dates follow the ISO 8601 standard, not EDTF. When recording century dates in addition to more precise dates, it is therefore necessary to repeat the 046 field.</span>
<span style="color:red>'''Conflicting dates'''</span>
<span style="color:red>In some situations, resources consulted may present conflicting dates (e.g., conflicting birth or death dates for a person, or start or end dates for a corporate body). In these situations, the 046 field should reflect the cataloger's evaluation of the conflicting date information. It is not necessary to record all the conflicting dates using field 046, nor is it necessary to give a 046 field for each resource consulted. Evaluation of the conflicting dates should generally result in a single 046 field, containing the date(s) the cataloger judges to be most accurate in representing the entity. At the cataloger's discretion, the date(s) recorded in that 046 field may incorporate the conflicting date information and need not correspond exactly to the date(s) selected for the authorized access point.</span>
<span style="color:red>Similarly, any dates added to the authorized access point should reflect the cataloger's evaluation of the conflicting date information, recorded in conformance with the instructions in RDA and the PFAN Policy Statements. If one date predominates in the resources consulted, that date may be considered the most appropriate to use in the authorized access point. If a single date does not predominate, the cataloger may decide to use the “approximately yyyy”, “yyyy?”, or “yyyy or yyyy” format in the authorized access point. In some cases, dates corresponding to the period of activity of the person (RDA 9.19.1.5) may be considered the best choice.</span>

(Same example as above, reflecting a different decision the cataloger might have made for recording 046 subfield $f)

<span style="color:red>Because the 046 field will be based on information from multiple sources, justification cannot be accurately expressed in subfield $v/$u at the end of the 046 field. The conflicting dates should be recorded in 670 fields. If an existing record has subfield $v/$u as 046 field justification, and the 046 field is being updated as described above, the subfield $v/$u should be removed, and the justification converted to a 670 field, if the conflicting dates are not already justified in an existing 670 field.</span>
<span style="color:red>'''DUncertain dates resulting from date calculations'''
<span style="color:red>In some situations, a calculation may be required to determine which dates to record in the 046 field and the authorized access point. Such calculations may result in uncertain dates.</span>
<span style="color:red>If the consulted resources provide only the person's date of death and their age (in years) at the time of death, as often happens with obituaries, their year of birth will correspond to one of two consecutive years. To calculate those years, first subtract the age from the year of death, then use the resulting year plus its preceding year as the two alternatives for the year of birth.</span>
<span style="color:red>''Examples :''
<div style="font-family:courier new; padding-right:25px; padding-left:100px; padding-top:10px; padding-bottom:10px; text-indent:-85px; line-height:1.4; border:1px solid #eaecf0; background-color:#f8f9fa;"><span style="color:red>

(Cataloger subtracted 75, the age at death, from 1994, the year of death; the resulting year, 1919, and the year preceding it, 1918, represent the two possible alternatives for the year of birth)
</div>
<span style="color:red>If non-Gregorian dates are found in consulted resources, uncertain dates may result from calendar conversion differences. Gregorian calendar dates are used in the 046 field and authorized access point. A single date in a non-Gregorian calendar may correspond to one of two Gregorian dates. </span>
<span style="color:red>''Examples :''
<div style="font-family:courier new; padding-right:25px; padding-left:100px; padding-top:10px; padding-bottom:10px; text-indent:-85px; line-height:1.4; border:1px solid #eaecf0; background-color:#f8f9fa;"><span style="color:red>
