How E-way Bill Validity is Calculated
Validity depends on distance. For normal cargo an e-way bill is valid for one day for the first 200 km and one more day for every further 200 km or part of it: 850 km is 5 days. For over-dimensional cargo, a single large piece above normal vehicle size limits, it is one day per 20 km.
A day does not mean 24 hours. Each day ends at midnight, counted from the date the bill is made: a one-day bill made at 10 pm on 4 November is valid till the end of 5 November, about 26 hours. Enter when you made the bill to see the exact expiry time.
