Should a converted Gregorian date replace the original Hijri date?

No. Keep both, with the calendar, conversion basis, uncertainty, and review status recorded.

Preserve Hijri and Gregorian dates in a Saudi matter chronology

Executive summary

Preserve the original date and calendar, then record any conversion separately. Do not let normalisation replace the evidence or determine a legal deadline automatically.

Identify the calendar used in the source.

Record uncertainty in ambiguous date expressions.

Verify legal calculations through the matter team.

Read the date in context

A Saudi matter file may contain Hijri and Gregorian dates, sometimes alongside document references or issue dates. Identify what each date describes before ordering events.

Record the source expression exactly and note the calendar where known. If the calendar or format is unclear, mark it for review rather than assuming.

Keep conversion as a separate field

A normalised chronology can help colleagues compare events, but it should preserve the original date and conversion basis. Record the method or authoritative reference used by the team.

Do not treat an unexplained software conversion as conclusive evidence. Material dates need verification appropriate to the matter and legal context.

Test a conflicting record

Suppose a letter shows two dates that appear inconsistent after conversion. Check the original image, text recognition, and whether the dates refer to different events.

Preserve the discrepancy and request clarification. A model should not silently select the value that makes the chronology look orderly.

Separate deadlines from events

Identify the legal or contractual trigger and calculation rule before deriving a deadline. Have the responsible lawyer confirm the applicable calendar treatment and other rules.

Put approved dates into the team's established deadline process. Timeline assistance does not replace legal calendaring or professional verification.

Make revisions traceable

Keep the original entry, corrected value, reason, and reviewer when a date changes. Identify any affected analysis or draft passage.

Give cross-border colleagues both the source date and reviewed normalised display. This lets them work with a consistent sequence while retaining access to the underlying evidence.
