How to convert indictions to weeks
To convert indictions to weeks, multiply the number of indictions by 782.6625. This factor is exact. To go the other way, multiply weeks by 0.001277689937 (rounded).

Months and years are not constant. This site uses the average Gregorian year of 365.2425 days, so one 'year' converts to 365.2425 days, not 365; use 'common year' for exactly 365 days.
About these units
Indiction (indiction)
A 15-year tax cycle introduced under the Roman Empire and used to date documents in the Byzantine and medieval worlds.
Indictions began as periodic reassessments of land or poll taxes in the Roman Empire, and the Latin indictio means an imposition or levy. Evidence exists for a 15-year cycle across the empire, a 14-year cycle in Roman Egypt, and a five-year cycle. Tax changes and arrears remissions tended to fall at the start of a cycle, with examples recorded under Nero in 58 AD and Hadrian in 118 AD.
Constantine is credited with turning the 15-year cycle into a dating system in 312 AD, and Egypt used it by 314 AD, though sources disagree on the first year, with one Coptic document implying 297 to 298. Justinian required indictions in dated documents in 537 AD. The year began on 23 September in the early Eastern Empire, later moving to 1 September, while Bede gives 24 September for the West and papal practice started on 25 December or 1 January. Because the length is a convention of 15 years, the figure used here is 15 Gregorian years, about 473.4 million seconds. The cycle also forms part of the 7,980-year Julian Period.
1 indiction = 473,354,280 seconds (exactly).

Week (wk)
Seven days. The seven-day week comes from the ancient Near East and is nearly universal in the modern calendar.
Nothing in the sky produces a seven-day cycle, which makes the week a human invention with a contested pedigree. Babylonians marked the 7th, 14th, 21st and 28th of the lunar month as special, but that was not a continuous cycle. A continuous seven-day cycle tied to the Sabbath is attested in Judaism by the 6th century BC at the latest, and scholars disagree on whether it was borrowed from Babylon or developed independently. The Romans later used a week named for the Sun, the Moon and the five visible planets, and in AD 321 Emperor Constantine decreed it across the empire.
A week is seven days, or 604,800 seconds, and it divides evenly into neither months nor years, which is why calendars shift against it. The ISO 8601 standard starts each week on Monday and assigns week 1 to the week containing the year's first Thursday, so some years have a week 53. Other societies used different lengths: Rome had an eight-day market cycle, and revolutionary France used a ten-day week from 1793 to 1802. The English word comes from Old English wice, meaning a turn or succession.
1 week = 604,800 seconds (exactly).
