Samaritan Day of the Year Calculator

Enter the date values and the tool computes the result for the samaritan calendar system.

1. 1

   Step 1

   Enter your date in the Samaritan calendar: day, month, and year.

2. 2

   Step 2

   We apply the Samaritan epoch and leap rules — a 13th leap month lands 7 times in each 19-year cycle.

3. 3

   Step 3

   Read the result exact to the day — Samaritan leap years (353–385 days) applied automatically.

• 1

  This Samaritan Day of the Year follows Samaritan calendar rules — its own epoch, month lengths, and leap years — so the result can differ from a Gregorian-based calculation of the same date; treat the calendar system as part of the input.

• 2

  Time zones can move a Samaritan date by a full day around midnight: today in one zone is still yesterday or tomorrow in another, so anchor the calculation to the zone your event actually follows before you enter anything.

• 3

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

• Intercalation is system-private: the Samaritan year runs 353–385 days because leap months follow rules no other calendar shares, so a Gregorian every-fourth-year reflex misreads samaritan dates. Let the tool apply the samaritan rule to a day-of-year number.

• Midnight and time-zone rollover flip whole days: a date near 00:00 belongs to the previous or next day depending on zone, which shifts day counts and weekdays computed under the Samaritan calendar. Fix one time zone for all inputs.
