Julian to Samaritan Date Converter

Enter a date in the Julian calendar and the tool returns the equivalent date in the Samaritan calendar using the standard relationship between the two systems.

1. 1

   Step 1

   Enter the complete Julian date — day, month, and year.

2. 2

   Step 2

   We apply both systems' rules: a Julian year runs about 365 days against the Samaritan 365 (≈0 days apart each year).

3. 3

   Step 3

   The result shows the correct Samaritan day, with Samaritan leap years applied date by date.

• 1

  Julian and Samaritan dates do not map one-to-one — the two systems start from different epochs and count leap years differently, so enter the full Julian date and read the Samaritan equivalent instead of shifting the year by a fixed offset.

• 2

  For deadlines tied to authorities or contracts, confirm which calendar the deadline officially uses before converting it here — a Julian–Samaritan date read in the wrong system can be off by days or even a full year.

• 3

  Leap rules differ between the calendars behind Julian–Samaritan, so a span that looks like whole years in one system can land a day or two off in another; trust the converted result rather than a fixed mental offset.

• The Julian and Samaritan calendars differ in year length and leap pattern, so a fixed-day offset — 365, 354, any memorized constant — drifts the Samaritan date badly. Convert the complete date so both leap rules apply.

• Epoch offsets are pair-specific: day zero of Julian and of Samaritan are different dates, and constants borrowed from another calendar pair are silently wrong by days or years. Use the Julian → Samaritan relation itself, not a remembered number.
