When Is Diwali 2026?

Diwali, the festival of lights, is observed on the new moon night of the Hindu month of Kartik. In the Gregorian calendar, this falls in October or early November. The main Diwali puja — Lakshmi Puja — lands in October 2026, preceded by Dhanteras and followed by Govardhan Puja and Bhai Dooj. The five-day arc is the most anticipated stretch of the Hindu calendar year.

For families who observe a strict puja schedule, the auspicious muhurat for Lakshmi-Ganesha puja varies by location. Consult a reliable panchang or your local temple for the precise timing published for the San Francisco Bay Area in 2026.

Foster City sits in San Mateo County on the western shore of the San Francisco Bay, one of the highest-concentration Indian-American professional corridors in the country. That density means Diwali here is community-driven, well-organized, and spread across multiple established hubs.

Temples and Community Hubs Near Foster City

The Foster City area draws on several Hindu institutions across San Mateo County and the wider Bay Area.

Sanatan Mandir, based in San Bruno, is one of the most established Hindu temples on the San Francisco Peninsula. Founded in 1986 and serving Indo-Fijian and broader Hindu Bay Area families, Sanatan Mandir organizes major puja programs for Navratri, Diwali, Holi, and Ram Navami across the year. During Diwali season, the mandir conducts multi-day Lakshmi Puja, Sukta chanting, and deepam rituals. Its deep roots in the community make Sanatan Mandir a reliable anchor for Peninsula families in Foster City and San Bruno alike.

Ashta Lakshmi Krupa, located in San Mateo, is the first Ashta Lakshmi temple in Northern California — a rare institution dedicated to all eight forms of Goddess Lakshmi. Operated under the non-profit organization SHIVA (Sanathana Hindu Dharma International Vedic Awareness), the temple makes Diwali observance especially meaningful: each of Lakshmi's eight aspects corresponds to abundance, prosperity, land, valor, knowledge, children, victory, and food. Devotees from Foster City make the short drive to San Mateo for special archana, Lakshmi Sahasranama recitations, and deepam offerings during the Diwali period.

Balaji Matha & Temple in the South Bay rounds out the options for Foster City families. Known for year-round Vedic programming that includes Rudra Abhisheka, Lalitha Sahasranama Parayana, Hanuman Chalisa, and Durga Puja, Balaji Matha & Temple organizes comprehensive Diwali programs featuring Lakshmi Sahasranama, special archana, and prasad distribution. Its multilingual programming serves the Tamil, Telugu, Kannada, and broader South Asian community across the Bay Area.

The Full Festival Season: Ganesh Chaturthi Through Bhai Dooj

Foster City's Hindu calendar builds momentum from late summer through early winter. The major milestones:

Ganesh Chaturthi (August or September): Ten-day installation of Ganesha murtis in homes and community spaces, with aarti programs morning and evening. Some Bay Area cultural associations organize collective Ganesh Chaturthi pandals. Visarjan events close the celebration.

Navratri (late September or early October): Nine nights of Devi worship anchored by daily aarti at Sanatan Mandir and garba dandiya events at community halls across San Mateo County. Gujarati associations on the Peninsula regularly organize garba nights that draw crowds in traditional chaniya choli and kurta attire.

Dussehra or Vijaya Dashami: The tenth day of Navratri, marking the victory of Rama over Ravana and the goddess's triumph. Cultural programs and symbolic Ravana dahan ceremonies appear in Bay Area communities around this date.

Diwali (October): Five days beginning with Dhanteras, moving through Narak Chaturdashi (Choti Diwali) and the main Lakshmi Puja night, and closing with Govardhan Puja and Bhai Dooj.

Kartik Purnima: The full moon about two weeks after Diwali. Some temples hold special deepdan (lamp-offering) and puja to close the festive season.

Home Puja on Diwali Night

Many Foster City families combine temple visits with a home Lakshmi-Ganesha puja on Diwali night. A standard setup includes a clean altar with deity images and fresh flowers, diyas lit along doorways and windowsills, sweets offered as naivedyam and distributed as prasad, and recitation of Lakshmi Puja Vidhi or the Ashta Lakshmi Stotram.

Indian grocery stores along El Camino Real in San Mateo County stock puja kits, diyas, rangoli powders, and mithai throughout October. Popular items — especially decorative lamps and pre-assembled puja kits — sell out in the days immediately before Diwali.

Insider Tip: Ashta Lakshmi Krupa sees very high demand for Lakshmi darshan on the evening of the main Diwali puja. Arrive at least 45 minutes before your intended puja time, or register for the morning session if an early slot is offered. Weekday Diwali celebrations at both Ashta Lakshmi Krupa and Sanatan Mandir are noticeably less crowded than the nearest weekend.
