Questions
- How is Porondam calculated?
- From each person's date, time and place of birth, using an astronomical calculation of the birth chart. Without a birth time the chart is less precise, and TrivianKnot tells you when it is.
- Is the site available in Sinhala?
- Yes. You can switch to Sinhala, Tamil or English at any time, and your choice is remembered on your account.
- Is TrivianKnot free?
- Yes. Creating a profile, browsing members and sending a limited number of interests is free. Plus ($5.39/month) adds identity verification, messaging, unlimited interests, the horoscope match and sharing your contact details. Premium ($10.79/month) adds a weekly profile boost, incognito browsing and advanced filters.
- Can my parents create my profile?
- Yes. A parent, guardian, sibling, relative or friend can create and manage a profile, and the profile says who manages it.
