Template:Associations/Orders of magnitude (time) To help compare orders of magnitude of different times this page lists times between 116 days and 1157 days or 3.2 years (107 seconds and 108 seconds).

• Shorter times
• 10 megaseconds = 115.74 days
• 128.6 days — half life of thulium-170

• 330 days — half life of vanadium-49
• 333.5 days — half life of californium-248
• 353, 354 or 355 days — the lengths of regular years in some lunisolar calendars
• 354.37 days — 12 lunar months; the average length of a year in lunar calendars
• ${\displaystyle \pi \cdot 10^{7}s}$ — The value of pi times 107 seconds is sometimes given as an approximate year value; it works out to 363.61026 days.
