On Sundays and National Holidays, Delhi Metro charges Rs 10 from 0 to 12 km, Rs 20 from 12 to 21 km, Rs 30 from 21 to 32 km and Rs 40 for beyond 32 km. So practically, if you own Smart Card you can get additional 10% discount over Smart Card discount. Total discount, 20% (10% + 10 %) would be there on Public Holidays and Sundays.
|Distance||Fare (Sunday and Holidays)|
|0-12 Kms||Rs 10|
|12-21 Kms||Rs 20|
|21-32 Kms||Rs 30|
|>32 Kms||Rs 40|
Those carrying a smart card and travelling during the off-peak hours — between 6AM-8AM, 12PM-5PM and 9PM onwards — will be able to avail a discount of 20 per cent. Other than Sundays and Holidays, if you have a Smart Card and are off-peak — from 6AM to 8AM, from 12PM to 5PM and from 9PM — then also you can benefit from a 20 percent discount (Smart Card Discount and Non peak hours discount).
