Every Sol (Martian Day) is equal to 88,775.244 Earth seconds. First day of Martian Peshutan Calendar starts at 10th of August, 1998 Iranian Standard Time. That day in Martian Peshutan Calendar (MPC) is considered the 1st of Martian calendar.
Earth Days and Mars Sols Passed Since the Epoch
Epoch: 1998-08-10 00:00:00 Iranian Standard Time
In this custom Mars system, 1 sol = 88,775 Earth seconds.
Formula for Earth days passed
Dearth = floor((t – t0) / 86400)
Formula for Mars sols passed
Dmars = floor((t – t0) / 88775)
Where
- t = current timestamp in seconds
- t0 = timestamp of 1998-08-10 00:00:00 IST
- floor() = round down to the nearest whole day or whole sol
If you want the exact fractional amount instead of whole days, remove the floor() part:
Dearth = (t – t0) / 86400
Dmars = (t – t0) / 88775
Custom Mars time structure: 1 sol = 5 Panjeh × 5 hours × 53 minutes × 67 seconds.
