The ability to set your current location (GPS) and local timezone is critical.
Not all digital calculators are built equally. To ensure your portable device or software provides accurate data for religious fasts (Vrats) and rituals, follow this verification checklist:

If you are shopping for a dedicated portable device or a high-tier Panchang application, look for these essential technical features: 1. Offline Core Algorithm
A Gregorian date is based on the Earth's rotation around the Sun (a solar calendar) and is fixed. A Tithi is based on the relative angular positions of the Sun and Moon (a lunar day) and varies in length and start time. The ability to set your current location (GPS)
Yes, most quality tools allow you to input any geographic location. The precision of the result depends on the accuracy of the location data (latitude and longitude) you provide.
For developers and advanced users seeking maximum control and precision, there are powerful programming libraries. You can work with , a .NET Core library for integrating tithi calculations into other software. For Python users, packages like nepali-panchang-utils provide functions to calculate Tithi, Nakshatra, Karana, Yoga, and even predict the Hindu month (Masa). The panchangam project on GitHub takes it a step further, generating monthly A3 PDF calendars and ICS calendar files that can be imported into any standard calendar app. Portability If you are shopping for a dedicated
